'With Jesus, we learn as a joyful family and flourish to be the best that we can be'
Mental Maths Monday!
28.4.20: Complete up to question 12 of the arithmetic paper below. Copy and complete the calculations in your book.
29.4.20: Complete the rest of the arithmetic paper.
Top Tips: Remember to complete this paper without using a number line or hundred square. You can draw your own number lines though, just like we have done at school or you can draw Base 10 if it helps.
For fractions of amounts, use your counting in 2s, 3s, and 4s. Remember, if it asks for something like two thirds of an amount, find one third then multiply by 2.
Remember, sometimes they try to trick us by arranging the calculation in a different way. For example, 13 + 7 = 20 or 20 = 13 + 7. The answer is the same (it needs to balance, = means the same as).
Sometimes, you can use the inverse relationship. For example, a missing number addition could be completed as a subtraction.
