Features

  • Every lesson of the unit, in the same kinds of question as the test
  • Pick the rectangle covered with no gaps and no overlaps, and count unit squares
  • Find an area in square centimeters, square inches or square meters and write the unit
  • Draw a rectangle with a given area on grid paper
  • Find the area of a tiled rectangle and of a rectangle from its side lengths
  • Solve an area story and a story with a missing side
  • Split a rectangle to multiply, and find the area of shapes made of two rectangles
  • Answer keys name the lesson and skill of every question

Skills Covered

  • Area as unit squares with no gaps or overlaps
  • Count square units: square centimeters, square inches, square meters
  • Draw a shape with a given area
  • Tiled rectangles: rows times squares in a row
  • Multiply the length by the width
  • Area stories, and finding a missing side
  • Split a rectangle to multiply (the distributive property)
  • The area of a shape made of two rectangles

How to Use This Pack

Two pages that go over the whole unit on area, to do together the day before the test. Its 11 questions are the same kinds as the test's, in the same order, with other numbers and shapes, so nothing on the review is on the test. There is no Score line: it is practice, not a grade. The pre-check and the unit test are packs of their own.

In the Classroom

Do the review together the day before the test, with square tiles or grid paper out. Work a question, then let students try the next one on their own, and stop on any that trip up more than a few. Question 3 asks for the unit and the stories want the answer with its unit, as on the test. The keys name each question's lesson, so a question the class misses points to the lesson to go back to.

At Home

Use the review as practice before a test at school. Find rectangles at home (a placemat, a tile floor, a book cover) and ask how many squares would cover it, then how to find that by multiplying.

Tips for Success

  • Area is measured in square units: say "square centimeters", not "centimeters"
  • Count the rows, count the squares in one row, then multiply
  • For a shape made of rectangles, find each rectangle's area and add
  • Keep square tiles or grid paper out
  • Go back to the lesson the key names for a question the class misses

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • 3.OA.B.5 Use the commutative, associative and distributive properties to multiply and divide, such as finding 7 × 8 from 7 × 5 and 7 × 3.
  • 3.MD.C.5a Know that a square with 1-unit sides has an area of one square unit and can be used to measure area.
  • 3.MD.C.5b Know that a flat shape exactly covered by some number of unit squares, with no spaces or overlapping, has that many square units of area.
  • 3.MD.C.6 Find an area by counting how many unit squares cover it, in square centimeters, meters, inches, feet or made-up units.
  • 3.MD.C.7a Tile a rectangle with whole-number sides and show that the number of tiles matches multiplying its length by its width.
  • 3.MD.C.7b Multiply length by width to get the area of whole-number rectangles in story and math problems, and picture products as rectangles.
  • 3.MD.C.7c Use tiles or area models to show that splitting a rectangle's side into two parts splits its area into two products (the distributive property).
  • 3.MD.C.7d Find the area of shapes made of rectangles by splitting them into separate rectangles and adding their areas, including in real problems.

3rd Grade Area Unit Review

A review of the unit on area, to go over together the day before the test. Students pick the rectangle covered with no gaps or overlaps, count square units and name them, draw a shape with a given area, multiply side lengths, solve area stories and find the area of shapes made of rectangles.
