Word Problem

Gr 3_OA_SubtractionAddition_WordProblem_Construct

This task is a set of addition and subtraction word problems with three follow up questions created for third graders. Double-digits are used in the word problems and students must decide for themselves when to use addition or subtraction through the construction of the responses. The follow up questions contain argumentative language and ask students to describe how they solved the problem, the warrants behind it, and a claim and evidence pertaining to a partner’s strategy.

Gr 3_OA_DivisionSingleDigit_WordProblem_Construct

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

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.
