Help your child count and underline the matching number sentence in the worksheet. Ask them if the total number of birds in each picture is odd or even, then check the correct box. When two equal numbers are added, the sum is always an even number (e.g. 2+2=4, 4+4=8, both divisible by 2).
The commutative property states that order of factors doesn't affect the product. Use it to help your kids solve simple problems. If they love birds, they'll love the colorful worksheet to identify exotic ones. Practicing is the best way to understand difficult topics. Look at the equations in this tracing sheet; help them draw a line to connect equations that match.
