Why you can take this page at face value

Straight from the KICD design

The strands and topics on this page are the Grade 8 Mathematics curriculum as the Kenya Institute of Curriculum Development sets it out. We have not chosen them, reordered them or left any out.

Nothing here is a sample

Every topic below is covered in our question bank, not a selection of the easy ones. The numbers beside each strand are the real counts.

Marked by a machine, written by a person

Each question carries its full working and a note on why every wrong answer is wrong, so a child who misses one is told what they were thinking, not just that they were wrong.
