McGraw-Hill My Math Kindergarten Answer Key Chapter 11 Two-Dimensional Shapes
Essential Question
How can I compare shapes?
Answer:
Can be the biggest or smallest angle, length … or specific order of angles+lengths. So reorder lines of one polygon (cyclic shift) so your shapes are compared from the ‘same point’ if they can. if not shapes are different. Then compare all lengths and angles. If any one value differs more than the accuracy value then shapes are different.
Am I Ready
Question 1.
Answer:
We need to circle the same shape.
Compare the shapes and circle the same shape.
The name of the shape is a circle.
Question 2.
Answer:
The matching shape is a triangle.
Triangle has 3 sides and 3 vertices.
Question 3.
Answer:
The matching shape is a circle.
The circle is a two-dimensional shape which is curved in a shape.
Question 4.
Answer:
The matching shape is a triangle.
Triangle is 3 sides and 3 vertices.
Directions: 1-2. Circle the objects that are the same shape. 3-4. Look at the shapes. Find the shapes in the row that are the same. Color them blue.
My Math Words
Review Vocabulary
Directions: Trace each word. Use the words to describe the objects in each box.
Answer:
The all books are the same size and the same length.
The earth is in circle shapes. It has no specific length.
The crayons are one small size and another one is larger in size. Therefore, their length is according to their size.
The pencils are one small size and another one is larger in size. Therefore, their length is according to their size.
The triangles are one small size and another one is larger in size. Therefore, their length is according to their size.
The squares are one small size and another one is larger in size. Therefore, their length is according to their size.
My Vocabulary Cards
Teacher Directions: Ideas for Use
- Group three words that belong together. Add a word that does not belong in the group. Ask another student to name the word that does not belong.
- Draw a line on each card every time you read or write the word in this chapter. Try to use at least 10 lines for each card.
Answer:

The wheel is in a circle shape. It has no sides and no vertices.
Round is also a circle shape.
The photo frame is a rectangle in shape. It has four sides and four vertices.
Triangle has 3 sides and 3 vertices.
The pencil is like a straight line.
The square has four sides and four vertices and all sides are equal.
Teacher Directions: Ideas for Use
- Have students sort the words by the number of letters in each word.
- Have students write o letter on the front and then draw o picture of on object that starts with that letter on the back.
Answer:
The triangle has three sides and three vertices.
The square has four sides and four vertices. All sides are equal in squares.
The rectangle has four sides and four vertices. Opposite sides are equal in rectangles.
My Foldable
Follow the steps on the back to make your Foldable.
Answer:
Take a piece of paper and cut it into shapes and fold them back.
The shapes are circles, rectangles, squares, and triangles.
The circle is a two-dimensional figure and it has no sides or vertices because it is a curved shape.
Rectangle: It has four sides and four vertices.
Square: It has four sides and four vertices.
Triangle: It has three sides and three vertices.
