  • Estimate and Approximate Homework Extension with answers for Year 5 Autumn Block 2

National Curriculum Objectives

Mathematics Year 5: (5C3) Use rounding to check answers to calculations and determine, in the context of a problem, levels of accuracy

Differentiation:

Questions 1, 4 and 7 (Varied Fluency)
Developing Use the numbers provided to fill in the calculations using approximation. Using up to and including 4-digit numbers, rounding to the nearest 10, 100 or 1,000.
Expected Use the numbers provided to fill in the calculations using approximation. Using up to and including 5-digit numbers, rounding to the nearest 100, 1,000 or 10,000.
Greater Depth Use the numbers provided to fill in the calculations using approximation. Using up to and including 5-digit numbers, rounding to the nearest 100, 1,000 or 10,000. Numbers are used within the context of lengths.

Questions 2, 5 and 8 (Varied Fluency)
Developing Match the statements to the correct approximations. Using up to and including 4-digit numbers, rounding to the nearest 10, 100 or 1,000. Rounding whole numbers only.
Expected Match the statements to the correct approximations. Using numbers with 2 decimal places (rounding to the nearest whole) in the context of money.
Greater Depth Match the statements to the correct approximations. Using up to and including 5-digit numbers, rounding to the nearest 100, 1,000 or 10,000. Numbers are used within the context of lengths.

Questions 3, 6 and 9 (Reasoning and Problem Solving)
Developing Find the largest possible difference between the approximate totals of one calculation by rounding to the nearest 10. Using up to and including 4-digit numbers.
Expected Find the largest possible difference between the approximate totals of two calculations by rounding to the nearest 10. Using up to and including 5-digit numbers, rounding to the nearest 10, 100, 1,000 or 10,000.
Greater Depth Find the largest possible difference between the approximate totals of two calculations by changing which place value the original numbers are rounded to. Using up to and including 5-digit numbers, rounding to the nearest 10, 100, 1,000 or 10,000. Numbers are used within the context of lengths.
