Maths Ninjas is our scheme to encourage children to learn their times tables. Each Maths Ninja rank has a coloured wristband that children can earn the right to wear.
Every week the children may try a Ninja grading. Children who get 11 sums correct in less than a minute are awarded the rank of Shodan; 22 sums correct in a minute is worthy of the white wristband and the rank of Nidan; and so on. Three children in school, Lucia Gonzalez-Odjidja, Caoimhe Rose and Angel Nwokporo have reached the rank of Kudan by correctly answering 99 sums in less than 2 minutes! Lucia achieved this feat when she was in Year 4.
The full rules and examples of the first few tests are given below.
