Features

  • Every lesson of the unit, in the same kinds of question as the test
  • Count the sides and angles of a shape and circle every pentagon
  • Draw a shape from a clue on dot paper and name it
  • Count the faces, edges and vertices of a solid
  • Name a shaded fourth, and find the squares cut into fourths, which can be different shapes
  • The second page (right angles, sixths and eighths, comparing unit fractions, lines of symmetry, perimeter and area) is for the states that teach them in 2nd grade
  • Answer keys name the lesson and skill of every question

Skills Covered

  • Count the sides and angles of triangles, quadrilaterals, pentagons and hexagons
  • Draw a shape from clues and name it
  • Count the faces, edges and vertices of a solid
  • Halves, thirds and fourths; equal shares can be different shapes
  • Right angles in a shape
  • Sixths and eighths; compare unit fractions
  • Lines of symmetry
  • Perimeter, and area from unit squares

How to Use This Pack

Two pages that go over the whole unit on shapes and equal shares, to do together the day before the test. Its 12 questions take every lesson of the unit in the same kinds of question as the test, with other shapes, so nothing on the review is on the test. Page 1 (questions 1 to 6) is the Common Core part of the unit; page 2 (right angles, sixths and eighths, comparing unit fractions, symmetry, perimeter and area) is for the states that teach them. Halves, thirds and fourths are named in words. 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 a box or a block out for counting faces, edges and vertices. Work a question, then let students try the next one on their own, and stop on any that trip up more than a few. Skip the second page if your class does not learn its lessons. 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. Ask your child to count the sides of a shape aloud, touching each one, and to show you how four fourths of a square can be different shapes.

Tips for Success

  • Have students mark each side as they count it, so none is counted twice
  • Keep a box or a block out for counting faces, edges and vertices
  • Equal shares are the same size, even when they are not the same shape
  • 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.
  • 2.G.A.3 Cut circles and rectangles into 2, 3 or 4 equal parts called halves, thirds or fourths; equal parts of one whole can look different.
  • 3.NF.A.1 Know 1/b is one of b equal parts of a whole, and a/b is a of those parts (denominators 2, 3, 4, 6 and 8).
  • 3.NF.A.3d Compare fractions of the same whole that have equal numerators or equal denominators, thinking about part size; record with >, = or < and explain.
  • 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.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.2 Divide shapes into parts of equal area and describe each part with a unit fraction, such as 1/6 of the shape.

2nd Grade Shapes and Equal Shares Unit Review

A review of the unit on shapes and equal shares, to go over together the day before the test. Students count sides and angles, draw a shape from a clue, count a solid's faces, edges and vertices, and name and find fourths.
