Features

Every lesson of the unit, in the same order as the test
Find the perimeter of a rectangle by adding the sides, and a missing side from the perimeter
Compare two rectangles with the same area and different perimeters
Decide whether a story asks for area or perimeter, then solve it
Count the right angles and pairs of parallel sides of a quadrilateral, circle every rectangle (squares too), and draw a quadrilateral that is not a rhombus, a rectangle or a square
The last four questions (shapes put together, lines and angles, lines of symmetry, and solids made of unit cubes) are for the states that teach them in 3rd grade
Answer keys name the lesson and skill of every question

Skills Covered

Find the perimeter of a polygon by adding its sides
Find a missing side from the perimeter
Rectangles with the same perimeter and different areas, and the reverse
Decide whether a story asks for area or perimeter

Right angles and parallel sides of quadrilaterals
Rhombuses, rectangles and squares (a square is both)
Draw quadrilaterals that are none of them
Polygons, lines and angles, symmetry and unit cubes

How to Use This Pack

Two pages that go over the whole unit on shapes and perimeter, to do together the day before the test. Its 11 questions take the lessons in the test's order, with other shapes and numbers; question 5 circles rectangles where the test circles rhombuses, and question 8 names shapes put together from two pieces. Questions 1 to 7 are the Common Core part of the unit, and questions 8 to 11 are state lessons, as 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 dot paper and unit cubes 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. Questions 8 to 11 are taught in 3rd grade in some states only: leave out the ones your class does not learn. 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. Walk around a table or a rug and count the steps for its perimeter, then count the tiles or squares that cover it for its area.

Tips for Success

Have students mark each side as they add it, so none is counted twice
Ask "around or covering?" before every area or perimeter story
A square is a rectangle and a rhombus too: have students say why
Keep dot paper and unit cubes 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:

2.G.A.1 Draw and spot shapes with given features, like a number of angles or faces, and name triangles, quadrilaterals, pentagons, hexagons and cubes.
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.D.8 Solve perimeter problems for polygons: add side lengths, find a missing side, and compare rectangles with equal perimeters but different areas, or the reverse.
3.G.A.1 See that shapes like rhombuses, rectangles and squares share features, such as four sides, that make them all quadrilaterals; draw quadrilaterals outside those groups.
4.G.A.1 Draw and find points, lines, line segments, rays, right, acute and obtuse angles, and parallel and perpendicular lines, including in flat shapes.
4.G.A.2 Sort flat shapes by whether they have parallel or perpendicular lines or angles of a certain size, and recognize right triangles as a group.
4.G.A.3 Find a line of symmetry, a fold line that makes two matching parts; pick out shapes that have one and draw their lines of symmetry.

3rd Grade Shapes and Perimeter Unit Review

3rd Grade3rd Grade Math Curriculum

A review of the unit on perimeter and quadrilaterals, to go over together the day before the test. Students find perimeters and missing sides, compare rectangles with the same area, decide whether a story asks for area or perimeter, and sort rhombuses, rectangles and squares.
