Posted on by

Ted and JP is a task designed for fifth graders in working on division and estimation. A problem is presented in which students must estimate a quotient, and students must critique two estimations and decide which is better. This requires students to critically think about how to make a good estimation. Students must state which estimation is better and explain the answer.

I used this task with my 3rd grade students. Students had been previously introduced to rounding numbers. This task was part of the introduction to estimation. In order to make a claim, students had to first round the numbers, and then add the rounded numbers to find the estimate. The task required students to state a claim and argument, as well as include what their partner said.
