Game Objectives

New Maths Curriculum:

Year 3: Add and subtract numbers with up to three digits, using the efficient written methods of columnar addition and subtraction

Year 4: Add and subtract numbers with up to 4 digits using the efficient written methods of columnar addition and subtraction where appropriate

Year 5: Add and subtract whole numbers with more than 4 digits, including using efficient written methods (columnar addition and subtraction)

Year 6: Solve addition and subtraction multi-step problems in contexts, deciding which operations and methods to use and why

KS2 Primary Framework:

Year 3:

Use practical and informal written methods to multiply and divide two–digit numbers. (Block A)

Develop and use written methods to record, support or explain addition of two–digit and three–digit numbers (Block A)

Year 4:

Develop and use written methods to record, support and explain multiplication and division of two-digit numbers by a one-digit number. (Block A and Block D)

Refine and use efficient written methods to add two-digit and three-digit whole numbers. (Block A)

Derive and recall multiplication facts up to 10 × 10, the corresponding division facts (Block B and E)

Year 5:

Refine and use efficient written methods to multiply and divide HTU × U, TU × TU, U.t × U and HTU ÷ U (Block A and Block D and Block E)

Extend mental methods for whole-number calculations, for example to multiply a two-digit by a one-digit number (e.g. 12 × 9), to multiply by 25 (e.g. 16 × 25). (Block A)

Use efficient written methods to add and subtract whole numbers and decimals with up to two places (Block A and Block B)

Year 6:

Calculate mentally with integers and decimals: U.t ± U.t, TU × U, TU ÷ U, U.t × U, U.t ÷ U (Block A)

Use efficient written methods to add and subtract integers and decimals, to multiply and divide integers and decimals by a one-digit integer, and to multiply two-digit and three-digit integers by a two-digit integer (Block A, Block B, Block D and Block E)

Use knowledge of place value and multiplication facts to 10 × 10 to derive related multiplication and division facts involving decimals (e.g. 0.8 × 7, 4.8 ÷ 6) (Block B)
