Today’s Task 1.Choose a set of pyramid cards, choose the set that will move your learning on. 2.Work out the expressions which go in each box of the pyramid. 3.If you can, write an equation for the final box. 4.If you can, solve the equation to find the value of the unknown number.

Today’s Task When choosing a set of pyramids, remember to choose the set that will move your learning on. (Look back at your Learning Journey.)

I can find missing numbers

I can find missing numbers

n = y = 3 n 4 = n 9 = n 54 = y 194 = 506 I can solve equations with unknowns on one side

a = n = 6a + 1 3a - 2 5a + 7 = 20a a 7 = a a 2 = a + 16 n 3n 4 = 2n + 34 I can solve equations with unknowns on both sides

Box 1 Contains an unknown number. Box 2 contains a number that is 5 more than the number in the first box. Box three contains a number that is 2 less than the number in the second box. The number in the top box is 28. Write an expression for each box. Write and solve the equation that will give you the value of the unknown number in box 1. Plenary
