Grade 3 – Special Thanks to Ms. Asari, Ms. Nelan and Ms. Bell from P.S. 103X for contributing to the creation of this task.
Big Ideas: MEASUREMENT: Some attributes of objects are measurable and can be quantified using unit amounts.
How many square inches will be shaded in on the paper once the person finishes?
- Watch the video. Tell (and record) what you notice. Ask (and write) questions that could help you figure out the answer to the above question.
- Develop a plan for answering the question. Think about how you will record and organized your information.
- Present a solution and justify your thinking.
Pedagogical Structures: Student self-selection of groups, Pairs Compare, Carousel Questions
Materials: rulers, graph paper, square tiles
Standard: Geometric measurement: understand concepts of area and relate area to multiplication and to addition.
Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.
