Math Monday - Number Sense and Numeracy

Numbers are used to describe quantities, to count, and to add, subtract, multiply, and divide. Understanding numbers and knowing how to combine them to solve problems helps us in all areas of math.

To try at home:
Play "Broken Calculator". Pretend that the number 8 key on the calculator is broken. Without it, how can you make the number 18 appear on the screen? (Sample answers:
  • 20 – 2, 15 + 3). Ask other questions using different "broken" keys.
