Gr 3_OA_EstimationAddition_Problem_Construct

Posted on by

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.

This task is used with third grade students. The task is an application of single digit division, but encourages students to draw a picture in order to construct an argument. The application asks students to distribute cookies to 5 people, given 15 cookies. Students must construct an argument by stating a claim and providing evidence. Students are then encouraged to engage in a pair-share and understand a partner’s thinking.

Gr 3_OA_AdditionSubtraction_WordProblem_Construct

Posted on by

I used this task with my 3rd grade students. The problems are basic addition and subtraction word problems. Although this is a concept students had previously learned at earlier grade levels, it is something that is good to spiral back to. Both problems gave students an opportunity to use regrouping. I had found that many of my students would tense up when seeing math word problems, and instead of showing their work or providing reasoning, would simply put a single number. This task forced students to actually show they reasoning and how they got to their answers, instead of simply writing “the answer.” The task also left room for students to discuss the findings with a partner and record how their partner solved them.
