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
The purpose of this activity is for students to identify the attributes that make a quadrilateral a rectangle, a rhombus, or a square. They do so by studying examples and non-examples, looking for features that each set has in common and drawing conclusions accordingly (MP7). The goal is not to craft the most precise definition for each, but to develop an understanding of the defining geometric attributes.
MLR8 Discussion Supports.
Display sentence frames to support small-group discussion: “I notice _____ so I think . . .”, “_____ and _____ are the same/alike because . . .”, “_____ and _____ are different because . . . .”
Advances: Conversing, Representing
Engagement: Provide Access by Recruiting Interest.
Optimize meaning and value. Invite students to share, with a partner, the attributes needed in order to be an example of this type of quadrilateral.
Supports accessibility for: Social-Emotional Functioning, Attention
Required Preparation
Create a chart with labels showing a rectangle, rhombus, and square for the lesson synthesis.
Launch
Groups of 2–3
Display the examples and non-examples of right triangles.
“The triangles on the left are right triangles. The ones on the right are not. Take a minute to think about their differences.”
“Then, choose all the shapes that are right triangles from the set labeled A–H. Write down what you think makes a shape a right triangle.”
1–2 minutes: quiet think time
1–2 minutes: partner discussion
Share responses.
“All triangles on the left and triangle E in the set are right angles. A triangle with a right angle is a right triangle.”
Activity
“Work with your group to analyze what makes a shape a rectangle, a rhombus, or a square. Each group will look at one type of quadrilateral.”
Assign each group one quadrilateral to analyze.
3–5 minutes: small-group work time
“Now, share your work with another group that worked on the same quadrilateral. Be sure to ask any questions you have about each other’s work.”
3–5 minutes: small-group discussion

Activity Synthesis
Invite 1–2 groups who analyzed rectangles to share their responses. Record their responses.
Ask the class:
“Do you agree with the shapes that are marked as rectangles (or rhombuses or squares)?”
“Do you agree with the descriptions?”
“Is there any part of the descriptions you’d say differently?”
“Is there anything you'd add to the description?”
When students have finished describing rectangles, highlight that: “A shape is a rectangle only if it is a quadrilateral with only right angles, and the sides that are across from each other are the same length.”
Repeat the discussion with rhombuses and squares.
