Which 2 choices represent an ODD number of objects?

• 
• 4 + 4

• 
• D) 2 + 2 + 1

• 

John split the rectangle into equal-size squares. Select 3 correct statements about the diagram.

• The total number of equal-size squares is 3 + 3 + 3 + 3 + 3.

• The total number of equal-size squares is 4 + 4 + 4 + 4.

• The total number of equal-size squares in the array is even.

• The total number of equal-size squares is 4 + 4 + 4.

• The total number of equal-size squares is 3 + 3 + 3 + 3.

Draw lines so the rectangle is completely filled with equal-size squares.

How many equal size squares are there?

For each image, determine whether there are an even or odd number of circles. Select the correct option.

• Even number of circles

• Odd number of circles

Count the number of dots in the diagram and write the total number.

• 10

• 5

• 12

• 8

For the number 8, decide whether the number is even or odd.

Write the number as the sum of 2 equal addends.

• 8 is even, 8 = 4 + 4.

• 8 is odd, 8 = 6 + 2.

• 8 is even, = 4 + 4 + 4.

• 8 is odd, 8 = 1 + 7.

For the number 13, decide whether the number is even or odd.

• Odd

• Even

For the number 18, decide whether the number is even or odd.

Write the number as the sum of 2 EQUAL addends.

• 18 is even, 18 = 9 + 9.

• 18 is odd, 18 = 12 + 6.

• 18 is even, 18 = 10 + 8.

• 18 is odd, 18 = 11 + 7.

Here are some pattern blocks that John and Gabby want to share. Explain why there are an even number of trapezoids.

• There are 10 trapezoids.

• There are 4 trapezoids.

• There are 5 trapezoids.

• There are 8 trapezoids.
