Placing Calculations on a Number Line - Mathsframe

Placing Calculations on a Number Line

Place the answer to calculations on a number line. An enormous array of choice. Addition, subtraction, multiplication and division. Ranging from adding numbers to 10 to multiplying 4 digit numbers. Great for combining teaching calculations and approximations with developing an understanding of place value.

Game Objectives

KS2 Primary Framework:

Year 3:

Round two–digit or three–digit numbers to the nearest 10 or 100 and give estimates for their sums and differences (Block A)

Use knowledge of number operations and corresponding inverses, including doubling and halving, to estimate and check calculations (Block D)

Year 4:

Add or subtract mentally pairs of two-digit whole numbers (Block A)

Use knowledge of rounding, number operations and inverses to estimate and check calculations (Block A)

Year 5:

Use knowledge of rounding, place value, number facts and inverse operations to estimate and check calculations (Block A and Block B)

Year 6:

Use approximations, inverse operations and tests of divisibility to estimate and check results (Block A and Block B)

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)

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