HOMEWORK: Prepare for Division Test

Hi Students,

This is a friendly remind that you have a Division Quiz on: Tuesday, April 25. 

On the quiz, you may be asked to: 

• Represent a division equation using a picture/array/Base Ten blocks
• Write a division equation to match a given picture/array/Base Ten blocks
• Solve division equations up to 2-digit by 1-digit using strategies, such as "Grouping Based On What You Know", or the "Expanded Algorithm" 
• Solve a Division word problem in pictures, numbers, and words (a sentence answer)

If you would like to practice, you are encouraged to go on to Mathletics and complete the following assignments: 

• Division Strategies (by 3s, 4s, 6s, 7s, 8s, 9s)
• Multiply & Divide (Related Facts 2, Fact Families)

If you have any question, please ask Ms Lacour.

From, 

Ms Elder and Ms Lacour

The "Grouping Using What You Know" strategy

Since this strategy is unfamiliar to many parents, I am going to describe it here using the language we used in class: 

1. Think about the problem. An example of what 48 / 4 means is that you have 48 of something, and you are sharing that out equally between 4 people.
2. Draw circles or stick people to represent the number of the divisor (4).
3. Use a number you can skip count by easily (like, 10, 5, 2...). Share out the same amount to each person/group. For example, in the picture, the student started by giving each person 3. 
4. Calculate how many you just gave out in total (3 + 3 + 3 + 3 = 12).
5. Subtract 12 from your dividend to see how much you have left to give (48-12 = 36).
6. Do steps 3 & 4 again until you have shared out all that you have. 
7. Count up how many you have in one of the groups. This is your quotient (answer).
