MATHEMATICS 5 CURRICULUM GUIDE 2015
Suggested Assessment Strategies
Resources/Notes
DIVISION
General Outcome: Develop Number Sense
Authorized Resource
Paper and Pencil
• 
Ask students to estimate 375 ÷ 4 using two different strategies and 
explain their choices.
(5N2.6)
Interview
• 
Ask students:
Angela and her three friends went shopping during the weekend.
They spent a total of $103.00. If each person spent the same
amount, about how much did each person spend? Explain your
estimation strategy.
(5N2.6)
Performance
• 
Bert’s class raised $234.00 as a class project. They are going
to share that money equally among three different charities. Ask 
students to estimate how much each charity will receive. Students 
could record their estimate on paper or individual white boards, and 
hold them up on cue. Students could share their strategies with the 
class.
(5N2.6)
Math Focus 5
Lesson 4: Estimating Quotients
TR: pp. 27-30 
SB: pp. 308-310
Snowball Division
Ask all students to write a divison fact on a piece of paper (e.g., 81÷ 9). 
They should crumple their paper into a ball. Teacher says, “Snowball 
fight!” and students throw their “snowballs”. Students pick up the 
closest snowball and determine the quotient. Repeat. This can also 
be done with related multiplication facts, writing a division problem 
to toss and solve, estimating quotients, etc. Teachers may wish to 
build in a verification step (tell the answer to your partner, check on a 
multiplication chart, check on your calculator) to ensure the answers are 
correct.
Variation: Use a dry erase marker to write math facts on an inflated 
beach ball. Students toss the balls back and forth with a partner. With 
each catch, the student is to give the answer to the fact closet to his or 
her right thumb. The facts can be wiped off and replaced as skill builds 
or to individualize for (add or decrease challenge) the needs of particular 
students.
