A knowledge check on multiplying three numbers for Year 4 maths, in four parts. Pupils calculate quick-fire questions like 2 × 3 × 4, explain which pair they would multiply first in 5 × 7 × 2, answer true or false on the rules of 0 and 1, then fill missing numbers such as 2 × __ × 5 = 40. Worked solutions are included. Matches the England National Curriculum mental multiplication objective.
