Lesson starts with a starter activity that checks prior knowledge on Pythagoras in 2D.
Independent investigation where you ask students to draw right angle triangles inside a cuboid, this is to identify the space diagonal.
Independent learning activity where students are asked to calculate the space diagonal, clues are given if necessary.
Differentiated worksheet with extension available.
Help sheet available to support independent learning.
Remember to do the starter on mini whiteboards to check for misconceptions when it comes to finding one of the small sides
