Missing Numbers

This resource contains five activities in which students are presented with a situation in which a digit, a number or an operator is missing. Students are required to complete the calculation.

Missing Digits 1: Students are presented with a series of two digit column additions and subtractions with digits missing from either the question or the answer or both.

Missing Digits 5: Students are required to complete a series of calculations in which digits are omitted from the calculation. The calculations are addition, subtraction, multiplication, division and calculating squares and cubes of numbers.

Missing Numbers 6: Students are presented with a calculation in which a number has been omitted. Students are required to find the missing number.

Missing Multiplications: Students are presented with a four by four multiplication grid which is partially completed. Students are required to complete the grid. In most cases students have to discover which numbers are being used on the outside of the grid in order to complete the body of the grid.

Missing Operations: Students are presented with calculations and answers with the operators missing. Students are required to insert the correct operators. Many calculations include the use of brackets.
