Such a cute idea from my daughter's preschool. Math Worms!
Easy enough to create a worksheet...Just draw a curvy line and a circle at the end. Help your Little by tracing the line with glue. Then she can line up her cheerios along the line and count how many treats can sit on a line. Then she can practice writing her numbers in the circle beside the line. Or write a math problem underneath and she can place the correct number of cheerios on the line and write the answer.
