Balance model for equations:
Solving in the Primary Grades.
Do the Balancing Act student activity
sheet, which can be downloaded from the Illuminations
site, and is also in D2L->Assignments-> Balancing Act
Do the Block Pounds activity sheet, which can be downloaded from the Illuminations
site, and is also in D2L->Assignments->Block Pounds
Do the rest of the assignment
solving equations with algebra tiles and pan balances:
Homemade Algebra Tiles to Develop Algebra and PreAlgebra Concepts
This assignment would have been to do a
couple of problems with both applets, record what you did, and then
tell which one you liked best and why....
