Kindergarten Mathematics Chapter 7 Teacher Guide and Answers

Kindergarten Mathematics: Chapter 7 | Shapes, Position, Sorting and Numbers

Separate teacher guide and answer key. Read the matching student chapter aloud, model a worked example, then let the learner respond independently. Keep individual student records private.

Day 1: Describe Flat Shapes

Instructional reading

A flat, or two-dimensional, shape has length and width. A triangle has three straight sides and three corners. A rectangle has four sides and four right-angle corners. A square is a rectangle whose four sides are equal. A circle has no straight sides or corners. When we turn or slide a shape, its number of sides does not change.

Model the concept

Show a triangle cut from paper, count three sides, and turn it. Explain why it remains a triangle.

Answer key

  • 1. How many straight sides does a triangle have? Answer: 3
  • 2. How many corners does a rectangle have? Answer: 4
  • 3. Which has no corners, a circle or square? Answer: circle
  • 4. Is every square also a rectangle? Answer: yes
  • 5. Does turning a triangle make it a new shape? Answer: no
  • 6. Draw and label a shape with four equal sides. Answer: A recognizable labeled square

Day 2: Describe Solid Shapes

Instructional reading

A solid, or three-dimensional, object has length, width and height. A cube has flat square faces; a ball is shaped like a sphere, which has a curved surface. A can is close to a cylinder, which has two circular faces and a curved side. Real objects may resemble shapes without matching perfect mathematical models.

Model the concept

Compare a dice-shaped cube with a ball. The ball rolls smoothly; a cube has flat faces and edges.

Answer key

  • 1. Which solid resembles a ball? Answer: sphere
  • 2. Which solid resembles a dice? Answer: cube
  • 3. What shape resembles a can? Answer: cylinder
  • 4. Does a cube have flat faces? Answer: yes
  • 5. Can a sphere roll? Answer: yes
  • 6. Name one real object that resembles a cylinder. Answer: can, paper roll, or another valid object

Day 3: Use Position Words

Instructional reading

Position words explain where an object is relative to another. Place a block above a book, below a table, beside a cup, or between two pencils. Left and right depend on a viewer’s orientation. Give directions clearly so a partner can repeat them with the same objects.

Model the concept

Put a cube between two blocks and describe its location aloud.

Answer key

  • 1. Where is an object placed between two chairs? Answer: between
  • 2. What word means next to? Answer: beside
  • 3. What is the opposite of above? Answer: below
  • 4. What word describes an object inside a box? Answer: inside
  • 5. Why might left and right depend on where you stand? Answer: The viewer’s orientation affects the direction
  • 6. Position a pencil beside a book and describe it. Answer: An accurate action and description

Score six core questions. Accept developmentally appropriate spoken or drawn equivalents, reteach missed skills, and check again without prompting.

Day 4: Sort and Count Objects

Instructional reading

We can classify objects by color, shape, size or other visible attributes. State a rule before sorting. For example, put all triangles in one group and all circles in another. Count each group carefully. The same objects could be sorted by color instead, but a new sorting rule creates new groups.

Model the concept

Sort a collection of red and blue buttons by color, then count each group without guessing.

Answer key

  • 1. Name one attribute used to sort. Answer: color, shape, size or material
  • 2. If there are four red buttons and three blue, how many buttons in all? Answer: 7
  • 3. Can objects be sorted by shape? Answer: yes
  • 4. Should you explain your sorting rule? Answer: yes
  • 5. Which group is larger, five or eight objects? Answer: eight
  • 6. Give a rule for sorting blocks into two groups. Answer: Any clear repeatable rule

Score six core questions. Accept developmentally appropriate spoken or drawn equivalents, reteach missed skills, and check again without prompting.

Day 5: Chapter 7 Independent Check

Instructional reading

Review flat shapes, solid shapes, position and sorting. Make a labeled drawing or use safe manipulatives before choosing an answer. Correct work uses the shape’s properties, not its size, color or orientation.

Model the concept

A cylinder has a curved surface and two circular faces. A triangle has three sides. Compare objects using those properties.

Answer key

  • 1. Which flat shape has three straight sides? Answer: triangle
  • 2. Which solid resembles a ball? Answer: sphere
  • 3. How many corners in a square? Answer: 4
  • 4. What does beside mean? Answer: next to
  • 5. Which is greater, 16 or 13? Answer: 16
  • 6. Explain one way to sort a group of classroom objects. Answer: Any clear attribute-based rule
