You can use this resource to work on 0-100 counting or counting by 10s.
Print out and laminate the truck and number sheets. Cut out each truck and the numbers. Option: You can use small magnets on the back of these if you wish to use them on a magnetic board.
Give them the trucks with the numbers you want to work on. For example, you may want to start with 0-20 or work on one set at a time.
Put the numbers in order under each truck. Have them count back the numbers when they are finished.
There is a worksheet that goes with each number set to help reinforce learning of the numbers. This is done through number writing practice, filling in the missing numbers and counting.
If learning to count by 10s, have them put the number trucks in order from 0-100 by tens.
The trucks can be hung on a wall along with the numbers in the correct order under each truck for visual learning and review.
