Representing, Comparing and Communicating Numbers

Grade 1: Represent and compare numbers to 31.
Grade 2: Represent and compare numbers to 50.

Today in math, students were given the tasks below. The first was a warm up task (minds on activity) where they got to represent 1 number of their choice with help from a partner. Then they shared their number with the rest of the class and how they represented it.
The second task students were told they had to pick 2 numbers from the numbers given but they could decide how they represented the numbers (students worked by themselves to complete this part and could use any resources available to them in the classroom). Students were also asked to explain which of the 2 numbers they chose was larger.

When students completed the task, their work went on our Math Bansho wall. We decided, as a class, which pieces communicated the answer to the task the best (easiest to see and understand) and why. 

Students decided that it was easiest to tell which number was larger when the 2 numbers were represented using the same tool (e.g. 10 frame). 

It was also decided that adding words and numbers to tell which one was larger and why also helped. 

We also discussed that Grade 2s expectation was to represent and compare numbers to 50 whereas Grade 1s expectation was to represent and compare numbers to 31.

Tomorrow we are going to repeat the lesson again. However we will use the criteria the students decided on above to help them communicate their answer when completing the task. What a great math discussion today!
