There was an equal number of boys and girls in the class at first. Halfway, another 12 boys came into the class and 8 girls left the class. In the end, there were twice as many boys as girls in the class. How many students were there in the class at first?


Thank you.

Hi

For P4 kids, a neat way is to use MD.

Hope this helps.

Best wishes

Hi

A likely way P4 kids would use will be MD.

There are alternate ways to present the MD.

As usual, I’ve drawn more MD than necessary, once students understand the logic behind the solution, they may consolidate the steps.

Mother's Day is just around the corner.

Wishing all sweetest, kindest and dearest mummies, be happy and healthy every day.

Best wishes

Hope this helps.
