8th Grade Growing Task Card Bundle
20 Task Cards dedicated to 8.EE.A.4 Operations in Scientific Notation
-Adding with like and unlike Powers of 10
-Subtracting with like and unlike Powers of 10
-Multiplying and Dividing
I designed these task cards to show students the uniqueness of each operation in scientific notation. Each set of 4 Task Cards uses the same 2 numbers, and students must perform all operations with these same two numbers. By isolating the differences between each card, my students were able to find much more success than simple worksheets.
