Help with counting, addition and subtraction
The Education Abacus can be used in your classroom to help with counting, addition and subtraction. We’ve used ours here to help children identify hundreds, tens and ones.
Using a Gratnells tray for storage is great, but they can also be used to create separate workstations for individual students or small groups. You can assign a certain amount of washers to each workstation and it makes for much easier tidying after the activity is complete.
Please refer to Edx Education Mathematics Manipulatives Reference Guide by Dr. Paul Swan for more information about how you can use the Abacus in your classroom.
