A recap of multiplying and dividing by 10, 100 and 1,000 for Year 5 maths, opening with the golden rule that digits move rather than zeros getting added. Pupils complete calculations like 450 ÷ 10, find the missing operations that turn 4.5 into 4,500, follow a two-step chain, then explain why adding zeros fails for decimals like 3.4. Answers are included. Matches two England National Curriculum objectives.
Number - multiplication and division
“Multiply and divide whole numbers and those involving decimals by 10, 100 and 1000”
The knowledge check works both whole numbers and decimals in both directions.
Number - multiplication and division
“Multiply and divide numbers mentally drawing upon known facts”
Every question is meant as mental work, not a written method.
An introduction box stating the key idea: digits move along the place value chart.
Calculations, missing-operation puzzles and a two-step chain like 150 ÷ 10 then × 100.
Pupils explain the decimal misconception, name what they found hard, and write a question for the teacher.
Solutions for all six questions.
