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
The purpose of this activity is for students to order numbers. Students estimate the location and label numbers on a number line, and then write them in order from least to greatest or greatest to least. For the third set of numbers, students may order the numbers using any method that makes sense to them. Students reflect on how the number line can help us organize numbers (MP5). Throughout the activity, monitor for the way students explain their reasoning based on place value and the relative position of numbers on the number line.
Representation: Access for Perception.
Use index cards, clothespins, and string to demonstrate the number line. Give students the numbers on the index cards and have them physically act it out by finding their place on the number line.
Supports accessibility for: Memory, Organization, Conceptual Processing

“Now you will have a chance to order numbers.”
“Sometimes you will put them in order from least to greatest, and sometimes it will be from greatest to least.”
10 minutes: independent work time
“Compare with a partner. Explain your thinking.”
5 minutes: partner discussion
Monitor for students who order the last set of numbers by:
explaining their reasoning using precise place value language
placing each number on the number line before ordering the numbers

Advancing Student Thinking
If students locate the numbers on the number line, but reverse the order given in the problem, consider asking:
“How did you decide the order of your numbers?”
“Does your list show the numbers in order from least to greatest or greatest to least?”
Activity Synthesis
Invite previously identified students to share their reasoning.
“How are the numbers you labeled on the number line the same as the list of numbers you wrote? How are they different?” (For least to greatest, its the same. The difference is the number line shows the distance between each number, but the list of numbers shows them right next to each other.)
