Warm up

Set a timer and see how long it takes you to answer these times table facts. Each day the same facts will be on the warm up slide… but in a different order. Can you get faster each day?7x4= 9x5=9x7= 12x3=3x9= 8x4=10x2= 6x8=11x6= 2x12=12x5= 7x7=

Moving on a grid. To move on a grid we need to use these instructions:right, left, up and down

For example:If we start at the red circle.We move two to the right we end up at 8,1Then we move three up. We are now at 8,4, the right angled triangle.

Activity two:Translate point A 3 down and 7 right.Translate point B 2 left and 6 down.Translate point C 5 up and 3 left.

Write the original coordinates of each point then write the coordinates of the new translated position.

Activity two: AnswersTranslate point A 3 down and 7 right.Translate point B 2 left and 6 down.Translate point C 5 up and 3 left.

Write the original coordinates of each point then write the coordinates of the new translated position.A = (2,5) to (9,2)B = (7,9) to (5,3)C = (8,1) to (5,6)

Activity three: Answers

No. A translation shouldonly change the positionof the shape and nothingelse. Here the translatedshape has changed sizenot just position.
