Problem/activity:
Task
Materials
One 10-frame per pair of students (see example below)
[IMG]
Counters, 10 per pair of students
Decks of number cards 0-5 (with 4 of each number) or two 0-5 dice
Setup
This activity is done in pairs. The students sit side by side with 10-frame and deck of cards or dice. If they have cards, the cards are shuffled and placed face down in front of them.
Action
Player 1 flips a card or rolls the die. They place that many counters on the 10-frame. Player 2 flips a card or rolls the die. They place that many more counters on the 10-frame next to the counters already on the ten frame. The students count the total together.
A recording sheet can be added when the students have been introduced to equations and number sentences. For those students who can handle higher numbers, a deck of 0-10 cards and two 10-frames can be used.
This game can also be played alone.

problem_activity: Narrative
In this activity, students recall what they know about division from grade 3. The context allows students to connect lived experiences to the math of the activity. By inviting students to consider treats that they enjoy in their homes or neighborhoods, they share experiences and foster connections that build community.
The first question gives students an opportunity to co-craft mathematical questions based on a situation before answering a question based on a division equation. Students divide a two-digit number by a one-digit divisor, as they did in grade 3, in a way that makes sense to them. The activity synthesis highlights different representations students made and relates them to the situation. The term
dividend
is re-introduced in this lesson to describe a number being divided into equal groups.

What mathematical questions can we ask about this situation?
Here is an equation:
\(84 \div 7 = {?}\)

Advancing Student Thinking
If students are unsure how to write a division question for
\(84 \div 7\)
, consider asking:
“If you were to act out the meaning of this expression, what would you do?”
“If you were to explain its meaning, what would you say?”
“In what type of situations would these types of actions take place?”
Activity Synthesis
Display two questions that students wrote for the equation
\(84 \div 7 = {?}\)
.
“What does the 84 represent in both problems?” (The amount being divided into equal groups.)
“In mathematics, the number being divided is known as the
dividend
.”
Invite students to share their strategies for the last question. Highlight strategies that show equal-size groups and reasoning that relates multiplication and division.
