Number Ladders teach number sense, place value, 2-Didit addition/subtraction skills, and the 100 chart. A great addition to the classroom!
Start at the bottom of the ladder and move up adding or subtracting as you write the sum or the difference on each step. You must be at a certain number when you reach the top!
Also added is a challenge, Reverse Number Ladders! Students see the numbers going up the ladder and they have to decide if it is adding or subtracting and how much it's adding or subtracting.
Number Ladders fit the needs of all students in the 2nd-5th grade classroom.
A total of 50 Ladders included!
