Month: June 2020

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

1. Please start by watching this informational video. You might have to watch it twice or three times. Subtraction with Regrouping – Math Video for 2nd Grade
2. Once you have watched the video, try the worksheet.

Use a calculator to mark your work. Use a pen to make corrections so that you can see where you made your mistakes. What do you notice about the mistakes you made?

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?

Optional: Try the spinner game on your own or with someone else in your family. The instructions can be found on page 2.
