Differentiation:

Set 1
Developing Given the area of the triangle, find the area of each individual square on the grid (either 1 or 2) by counting the squares.
Secure Given the area of the triangle, find the area of each individual square on the grid (any whole number) by counting the squares.
Mastery Given the area of the triangle, find the area of each individual square on the grid (whole numbers and halves) by counting the squares.

Set 2
Developing Determine which 2 out of 3 right-angled triangles have the same area on a grid where each square is 1cm².
Secure Determine which 2 out of 4 triangles have the same area on a grid where each square is 1cm².
Mastery Determine which 3 out of 4 triangles have the same area on a grid where each square is 2cm² or 5cm².

Set 3
Developing True or false statements based on finding the area of right-angled triangles from rectangles with double the area. Whole numbers and no conversion used.
Secure True or false statements based on finding the area of right-angled triangles from rectangles with double the area. Decimals (.5) and direct conversion used.
Mastery True or false statements based on finding the area of right-angled triangles from rectangles with double the area. Any decimals and any conversion used.

Set 4
Developing Given the area of a whole wall, finding the area of one right-angled triangle brick in the wall. Whole numbers and no conversion used.
Secure Given the area of a whole wall, finding the area of one right-angled triangle brick in the wall. Decimals (.5) and direct conversion used.
Mastery Given the area of a whole wall, finding the area of one right-angled triangle brick in the wall. Any decimals and any conversion used.

Set 5
Developing Determine whether the area of a triangle is correct or incorrect and explain any mistakes. All lengths are given in whole numbers.
Secure Determine whether the area of a compound triangular shape is correct or incorrect and explain any mistakes. Overall height and base lengths are given. Some conversions between mm/cm or cm/m necessary.
Mastery Determine whether the area of a compound triangular shape is correct or incorrect and explain any mistakes. Overall height and base lengths, as well as some unnecessary lengths for the calculation are given. Some conversions between mm/cm and cm/m necessary.

Set 6
Developing Find the area of three right-angled triangles, where all lengths are in whole numbers. Put the triangles in order according to their areas.
Secure Find the area of four triangles, where all lengths are whole numbers and either cm or mm. Put the triangles in order according to their areas (some conversions between cm and mm will be necessary.)
Mastery Find the area of four triangles, where all the lengths are whole numbers or decimals, and either cm or mm. Put the triangles in order according to their areas (some conversions between cm and mm will be necessary).
