The Concept:  Estimating and making predictions are valuable skills that foster critical thinking in young children. As children develop number sense, they will also develop their ability to estimate. The more children have opportunities to practice estimating, the better their estimating skills will become. Even young children can make predictions—the fun is in the guessing!

This activity provides ideas for making estimation part of your daily routine. Along with estimation, the children will sort items by size and will count the items in each category.
