Before going further into doing anything else involving numbers, your kids must first learn to count. Guide them through their 1, 2, and 3s and then take it a bit further into the tens, and then the 100s. With the right equipment and learning materials such as this colorful worksheet, your kids will be counting as high as possible. Look at the trucks in the printout and count the barrels on them together with your kids. Now, help them circle the trucks that have 10 barrels.
