Number Ladders 2-Digit Addition/Subtraction are great for math centers. They practice number sense, the 100 chart, and 2-digit addition/subtraction skill, .
Students start at the bottom of the ladder and add or subtract as they move up the ladder. They must be at a certain number when they reach the top of the ladder. Also included is a challenge, Reverse Number Ladders. Students see the numbers going up the ladder and have to determine if the numbers are adding or subtracting and by how much. A great addition to the classroom to reach all learners.
