Strategies
This exercise is possible to get accuracy badges because the steps are clear. The speed badges are probably medium at this stage because of the multiple steps that are needed to arrive at the final answer.
- The template is generally , , , then answer. In other words, the first two slots are filled in with the same thing.
Real-life Applications
- Multiplication is needed and used by mechanics for repairing cars by multiplying when they overhaul the engine, measure the pistons or just to put in a new gearbox or engine.
- By learning multiplication and memorizing the times tables, students provide themselves with essential building blocks to do higher learning math, like division, fractions and even algebra.
