4 Elaborate

Activity: Presenting

After assuring that the students understood the concept and are able to compare two numbers, put an addition problem on one side and a whole number on another side; then, teach the students how to compare them by doing an example on the board. Example, compare 11+1 with 9; then, show them how to do it.

Later on, write two addition problems on both sides. Example, compare 10+2 with 12+1. Do some examples on the board; then let the students do the other ones.

Apply the same concepts with subtraction.


Student Instructions

Explain more after each example, if needed.

Then, give the students a homework assignment about comparing numbers to assess their understanding.

After one week of practice, give the students a test to assess their knowledge.
