Conditions for congruent triangles Use Powerpoint to remind pupils of conditions for congruent triangles and complete questions from Slide 5 and Slide 6 (worksheet available on powerpoint) Powerpoint lesson (shape and space - congruent triangles) Main - complete any of the below exercises on congruent triangles. Collins ex 6A page 139 Brown ex 29.4 page 348 Homework: Elmwood Revision Sheet 57H Alternatively: My maths link-shape-congruency-congruent triangles. Opportunity for independent learning - pupils work through the slides completing tasks to find which conditions give congruent triangles ck |

| 2 | Finding lengths in similar shapes (Set 3) Starter - finding lengths in similar triangles using Easiteach lesson ck Main: similar triangles matching cards - find which triangles are similar by matching the angles and then find the missing sides - multiplying by scale factor to find the larger side and dividing by scale factor to find the side from smaller shape. See ck for cards at least one day prior to lesson. Plenary - slides 7 and 8 - mymaths link - identifying which triangles are similar and finding missing lengths or (Set 1 and 2) Starter - use Powerpoint - Shape and space - similar triangles - slides 2 to 5 to recap finding a missing length. Main: Identifying which triangles are similar and finding missing sides - use Powerpoint slides 6 to 12. Exercise: Collins ex 12A page 294, ex 12B page 297 and ex 12C page 297 - select as appropriate. Brown ex 37.2 page 430 and ex 37.3 page 432 Plenary: More difficult questions - Powerpoint slide 14.
