To keep up your skills in Math, you may want to practice by playing some games. You can say the numbers in French and practice your counting/skip counting. Here are some activities you could try:

• Adding prices at the grocery store
• Math minutes (how many addition to 20 questions can you answer in 1 minute… in 2… in 5? What abut Subtraction?)
• Creating patterns with objects found indoors and outdoors
• Creating patterns with beads or string while making jewelry/friendship bracelets
• Following patterns by learning how to crochet or knit: https://www.youtube.com/watch?v=Cjo13OyjZgo
• Measuring ingredients in baking (with the help of an adult): http://projectchef.ca/recipes/
• Measuring ingredients in Science experiments (with the supervision of an adult)
• Measuring objects around the house
• Building a project that requires measurements (sewing, bird house, etc)
• Shape scavenger hunts 
• Number puzzles, Sudoku
• Play card games: Go Fish, War, Snap etc

Here are some optional activities that review some of the topics we learned this year: 

1. Estimation 

Before counting, estimate the total of each item

Count the number of items. What strategy did you use to count the total of items. What steps did you take to figure out the total?

estimation

2. Graphing

Over the course of the week, record everything you eat on the graph. If you eat a fruit color in or draw the fruit you ate under the fruit column. If you had something sweet (cookie, muffin, ice cream, pop, bubble tea etc.), color or draw the item you ate under the desert column.  Keep this graph next to your kitchen table to help you remember to record your food.

3. Measurement

Using fishy crackers or another non-standard unit of measurement about equal length and complete the following worksheet.

Here are the instructions in English

1. Measure the right side of the page. How many crackers did you need to measure the right side of the page.
2. Measure the left side of the page. How many crackers did you need to measure the left side of the page.
3. What did you notice?
4. Measure the bottom side of your page. How many crackers did you need to measure the bottome

*** How many will you need to measure the length around the page? (Bonus not on the page)

4. Measurement

Get your favorite snack (fishy crackers, cereal, chips, bear paws, yogurt etc.)

Can you find the nutritional information on the back. It looks like this.

Look to see how much sugar/sucre your treat contains. It will be measured in grams

4g of sugar=  1 teaspoon of sugar

Can you figure out how many teaspoons of  sugar are  in your treat? Measure the sugar  with a teaspoon.

A can of coke has 39 grams of sugar. How many teaspoons is that? Can you measure that out?

5. Subtraction and addition practice 

Option 1

Shake, Drop, Add: You will need 5 (or more) coins each. Hold all coins in a closed fist. Shake your hands and count to 3. On 3, drop your coins in front of you. For each coin that lands heads  up, you score 5 points. For each coin that lands tails up, you score 2 points. If you are playing with a partner total your points to see who has the greater score and play again until someone get to 100.   If you are playing alone, play until you reach 100, and tally how many hands it took you took to get to 100. After a few rounds, you might change the number of coins you play with and/or the number of points scored for heads and tails. Remember that you can always use a 100’s chart or a 100 object to help you with your counting.

Option 2

Shake, Drop, Subtract:You will need 5 (or more) coins each. Hold all coins in a closed fist. Shake your hands and drop your coins in front of you. This time you are counting down from 100. For each coin that lands heads up, you take away 5 points. For each coin that lands tails you take away 2 points. If you are playing with a partner the person who arrives at 0 first wins. If you are playing alone, play until you reach 0, and tally how many hands it took to you to get to 0 . Remember that you can always use a 100’s chart or a 100 object to help you with your counting.

Option 3

Yathzee (you will need five dice for this game)

Each player rolls five dice and then chooses whether to re-roll any of those dice. The best roll is a yahtzee, where all five dice have the same value. After three total rolls, the player then determines which scores she qualifies for with her roll.

Here is short video explaining that game: https://www.google.com/search?client=safari&rls=en&q=yahtzee+rules+for+kids&ie=UTF-8&oe=UTF-8

3. Word question:

1 dollar

2 dollar

5cents

10 cents

25 cents

Option A: 6,75$

On non! Sylvie a cassé sa tirelire/piggy bank. Toute sa monnaie est tombée! Elle avait 6 dollars et 75 sous. Dessine 6,75$ avec le moins de pièces possible. Dessine 6,75$ avec le plus de pièces possible.

Oh no!  Sylvie broke her piggy bank. All her money fell to the ground. She had $6.75. Can you represent $6.75 with the least amount of coins  possible. Can you represent $6.75 with the most amount of coins and bills possible.  You can draw your answer. You can also  cut and paste the coins from the play money below to help you organise your work.

675 (2)

Option B: 0,65$

On non! Sylvie a cassé sa tirelire/piggy bank. Toute sa monnaie est tombée! Elle avait 0,65 sous. Dessine 0,65¢  avec le moins de pièces possible. Dessine 0,65¢ avec le plus de pièces possible.

Oh no!  Sylvie broke her piggy bank. All her money fell to the ground. She had 0,65¢. Can you represent 0,65¢ with the least amount of coins possible. Can you tepresent 0,65¢ with the most amount of coins possible.  You can draw your answer. You can also  cut and paste the coins from the play money  below to help you organise your work

065¢

4. There is another strategy for subtracting with regrouping called Make it Round. The idea is that if you are subtracting only 10’s and no 1’s, your equation will be easier to solve (for example 43-20 is easier to solve than 41-18). In this case, you add the same number to both your minuend and subtrahend (the number you are subtracting from and the number you are subtracting) so that your subtrahend is “round” (10/20/30/40 etc). Here is an example:

35-19 

(35+1)-(19+1)

36-20= 16

Practice: Can you make the following equations round?

28 + __ = 30

46 + __ = 50

59 + __ = 60

46 + __ = 50

Activity: Try using this strategy to solve the following questions. Remember- how much do you need to add to each number to make the subtrahend “round” (a multiple of 10). Parents I have attached the answer key at the bottom.

45 – 19 =

56 – 18 =

33 – 17 =

47 – 28 =

61 – 49 =

75 – 28 =

Game: The Biggest Difference

Math activities week #9: Larger number subtraction (without regrouping)

We have not covered this concept in class yet. Some of you might already know how to subtract larger numbers, but for others this might be a new concept. It might be challenging at first. Remember you can use a 100’s chart to help you. You can draw pictures to help you and you can use object from around the house. Please do not use a calculator.

1. Practice your subtraction strategies with 1’s using this game: https://www.mathplayground.com/ASB_IslandChaseSubtraction.html

Having a strong understanding of your addition and subtraction strategies to 20 will help with speed and accuracy as you move on to larger numbers.

2. Watch the following video on subtraction: https://www.youtube.com/watch?v=8HIPTYXhArk

3. Complete the following worksheet using the above strategy

Mad-Minute-Double-Digit-Subtraction

4. Word Problem: You have 100 cents (or 1 dollar) to spend at the candy store. Below is the list of prices. What treats can you get with 100 cents? Use words, drawings and/or equations to answer the following question. You may buy multiples of a certain candy if you want. How much money do you have leftover? What is the largest amount of treats you can buy with 100 cents?

Choose something inside or outside of your house to measure. Measure it in as many ways as you can think of. Record (in drawing, writing or on the following worksheet) at least 5 different measurements.

Optional worksheet: 

measuring penny

3. A “unit of measurement” is what you use to measure something. Standard units of measurement include cm, mm, m, km, inches, ft, lbs, grams, cups etc. They are more widely recognized and can measure different attributes of an object such as weight, size or volume. Non standard units of measurement can be anything you use to compare measurement. For example: My phone is the same length as my hand. My table measures 7 pens wide.

• longueur/Length: how long something is
• largeur/Width: how wide something is (the smaller sides on a rectangle)
• hauteur/Height: how tall something is
• Volume: used to measure liquids
• poids/Weight: how heavy something is
• plus grand que/bigger than
• plus petit que/smaller than
• la même taille que/the same size as

Choose 5 objects to measure. Measure each object using a different “unit of measurement” (standard or non standard). Find at least one object that is plus petit que ton ongle and one other that is plus grande que ta jambe. Record the object, measurement and unit of measurement for each. Which is the biggest? Smallest? How do you know?

Here is an optional worksheet to help you organised your findings: 

measurement table

4. Which of these measurement tools do you think does not belong? Why? Please video or audio record your answer (in French) and send it to me. Give me one answer that you think a lot of students will think of. Now can you come up with an answer that you don’t think many students would have?

Addition and subtraction to 20 Review

1. Go Fish – Doubles Materials – deck of playing cards, take out the face cards Like the regular Go Fish game, but when you get a pair, in other words, a double, you need to say what the sum is. Ex. If you have a 6 in your hand, ask the other player “As-tu un 6? (our) 6 et 6 font 12” The player who has the most doubles wins!

2. Complete the addition and subtraction to 20 worksheets below. Think about the strategies we learned in class (doubles, voisins, presque voisins, faire 10, + 9, -9, à zero etc). If you are unable to print the worksheet, copy or write out your own equations. 

“Math Minute Challenge”: If you are looking for a challenge, time yourself and see how many questions you are able to answer in 5 minutes. How about 1?

addition et soustraction a 20

3. Probleme: Tu achètes 20 fruits. Quelques-uns sont des pommes, quelques-uns sont des bananes et quelques-uns sont des oranges. Combien de chaque fruit peux-tu avoir? Explique avec des mots, des dessins ou des objets. You buy 20 fruits, some are apples, some are bananas and some are oranges (feel free to add other fruits to the mix!). How many of each fruit could you have? Explain your thinking with words, pictures, or objects.

4. Look at the Example 1 and example 2. Can you create your own subtraction story?

Example 1 La nuit d’Halloween, j’ai ramassé 32 barres de chocolat. J’adore le chocolat. Pendant la nuit mon papa a mangé 6 barres de chocolat. Combien de barres de chocolat restent t-il?

Example 2 Il y a un grand arbre devant ma maison. Il y 15 oiseaux qui chantent dans l’arbre. 5 oiseaux s’envolent. Combien de oiseaux restent t-il?

Math Activity #2: Number Sense Review

FRENCH NUMBERS 0-100 – REFERENCE LIST

1. Listen to the story “En Safari” through Pearson’s Mathology Series: https://schmedia.pearsoncanada.ca/mlb/index.html?code=11NI-FR

Complete the activity that comes up. “How many tiles?” Create a drawing using as many different coloured tiles as you wish. Tell me how many tiles of each colour you used and how many in total. Don’t forget to save your image and send it to me!

2. Complete the “Greater Than/Less Than” worksheet below and send it to me. If you are unable to print the worksheet, you can write the questions (or create your own) on a piece of paper.

= means equal. Use this symbol when the numbers are the same. Ex 36 = 36

> or < are used to indicate which number is bigger. Think of this symbol as a hungry alligator who wants to eat the bigger number. This way the triangle is always open towards the bigger number and pointing towards the smaller ex 36 > 14 or 2 < 9

Practice saying the equations out loud using vocabulary in French:

• Plus que/more than
• Moins que/less than
• Égal à/equal to

Ex. 12 est plus petit que 20 

greater-than-less-than-equal-to-1

3. Play the card game “War”: The deck is divided evenly among players. Players draw the top card from their pile at the same time. Players must say the numbers in French. The biggest number wins and takes both cards for their “winnings” pile. When both players run out of cards, the player with the most cards in their “winnings” pile wins! 

4. Practice grouping 10’s and 1’s in this place value game: https://www.topmarks.co.uk/learning-to-count/place-value-basketball

5. Teach someone in your family how to play the “Digit Game”. We will review how to play this game during our conferences this week. Here are the instructions:

One person picks a number, writes it down and hides it. The second person has to guess the number. Write down each guess in the left column. In the second column you will write how many numerals (out of the two) are guessed correctly and in the third column you write how many of those numbers are in the correct digit (10’s and 1’s place). The game continues until the second person guesses correctly. Once students have a good understanding of how this game works they are able to use strategy to guess the correct number. Here is an example of how the game could look.

*numbers must be double digit (between 10 and 98) with no repetition (ex 99)

Secret number: 24

*Bonus Activity: Go for a walk. Look at the house numbers in your neighbourhood: what do you notice?
