Students can practice using this strategy to help them with addition!Students learn to expand the numbers to add them up. Helps them add up 3-digit numbers using a new strategy.
How to Use:
Students will match the algorithm with the expanded form. On the recording sheet, they can then write down their matches and solve the addition problem. An example is given for them. Perfect for math stations or independent work.
Cards can also be used to play memory--matching the algorithm with the expanded form.
Print the matching cards on cardstock and laminate for them to last longer :)
