Go ahead and dowload all of the Number Monster files to the left.
Each file contains an image of each number monster.
Once your child has memorized what each number monster looks like, they can then switch from using their fingers to count to counting each number monster's features. When your child sees the number 4 in a math problem, they can then superimpose what the number monster looks like in their head and count the monster's features.
Once your child is used to "seeing" the number monsters - math becomes much easier.
