  1. Please start by watching this informational video. You might have to watch it twice or three times. <\/span>Subtraction with Regrouping – Math Video for 2nd Grade<\/span><\/a><\/li>\n
  2. Once you have watched the video, try the worksheet.\u00a0<\/span><\/li>\n<\/ol>\n

    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?<\/span><\/p>\n

    1. Word question:<\/span><\/li>\n<\/ol>\n

      1 dollar<\/a><\/p>\n

      2 dollar<\/a><\/p>\n

      5cents<\/a><\/p>\n

      10 cents<\/a><\/p>\n

      25 cents<\/a><\/p>\n

      Option A: 6,75$<\/span><\/p>\n

      On non! Sylvie a cass\u00e9 sa tirelire\/<\/span>piggy bank.<\/span><\/i> Toute sa monnaie est tomb\u00e9e! Elle avait 6 dollars et 75 sous. Dessine 6,75$ avec le moins de pi\u00e8ces possible. Dessine 6,75$ avec le plus de pi\u00e8ces possible.<\/span><\/p>\n

      Oh no!\u00a0 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\u00a0 possible. Can you represent $6.75 with the most amount of coins and bills possible.\u00a0 You can draw your answer. You can also\u00a0 cut and paste the coins from the play money below to help you organise your work.<\/span><\/p>\n

      Oh no!\u00a0 Sylvie broke her piggy bank. All her money fell to the ground. She had 0,65\u00a2. Can you represent 0,65\u00a2 with the least amount of coins possible. Can you tepresent 0,65\u00a2 with the most amount of coins possible.\u00a0 You can draw your answer. You can also\u00a0 cut and paste the coins from the play money\u00a0 below to help you organise your work<\/span><\/p>\n

      1. There is another strategy for subtracting with regrouping called Make it Round. The idea is that if you are subtracting only 10\u2019s and no 1\u2019s, 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 \u201cround\u201d (10\/20\/30\/40 etc). Here is an example:<\/span><\/i><\/li>\n<\/ol>\n

        35-19\u00a0<\/span><\/i><\/p>\n

        (35+1)-(19+1)<\/span><\/i><\/p>\n

        36-20= 16<\/span><\/i><\/p>\n

        Practice: Can you make the following equations round?<\/span><\/p>\n

        28 + __ = 30<\/span><\/p>\n

        46 + __ = 50<\/span><\/p>\n

        59 + __ = 60<\/span><\/p>\n

        46 + __ = 50<\/span><\/p>\n

        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 \u201cround\u201d (a multiple of 10). Parents I have attached the answer key at the bottom.<\/span><\/p>\n

        45 – 19 =<\/span><\/p>\n

        56 – 18 =<\/span><\/p>\n

        33 – 17 =<\/span><\/p>\n

        47 – 28 =<\/span><\/p>\n

        61 – 49 =<\/span><\/p>\n

        75 – 28 =<\/span><\/p>\n
