Here is a fabulous instructional activity on subtracting decimals with different numbers of decimal places. There are teacher-led activities for learners to engage in, including, modeling decimal subtraction through decimal squares, looking at place value, seeing patterns in decimal numbers, and finding decimal values on a number line. Then, pupils pair off and play an interactive online game that further reinforces the concepts being taught. Finally, each pupil completes a series of worksheets that are embedded in the plan to gain further practice. An outstanding math lesson plan which should lead to meaningful learning.
