KPI 7.01: Understand and use place value for decimals, measures and integers of any size

• Read and write large numbers up to 1 billion and small numbers down to 0.001 (13, 45)
• Understand and use place value for decimals, measures and integers of any size (3)
• Understand definitions of odd and even (25)
• Understand definitions of product and sum
• Order positive and negative integers and decimals (37, 46)
• Use the symbols =, ≠, <, >, ≤, ≥  for positive integers and decimals
• Powers (2, 3, 4, 5, 10, roots (basic), ordering positive and negative numbers and use of inequality symbols

KPI 7.02: Use Addition and Subtraction, including formal written methods, applied to integers, decimals 

• Perform simple calculations using mental methods: partitioning, compensation, bridging (1 – 12)
• Add and subtract large integers (18 – 20)
• Add and subtract decimals (47)

KPI 7.03: Calculate and solve problems involving perimeters of rectangles and compound shapes (not circles)

• Use standard units of length including decimal quantities, powers and roots
• Derive and apply formulae to calculate and solve problems involving perimeter of triangles, parallelograms, trapezia (549 – 551)
• Given the Perimeter, find the possible values of  missing lengths (simple rearrangement of formulae involving Perimeter) (552)

KPI 7.04: Estimate calculations by rounding

• Round numbers and measures to an appropriate degree of accuracy [nearest 1, 10, 100 or 1000 or nearest 0.1, 0.01 or 0.001] (17, 56)
• Use approximation through rounding to estimate questions in context e.g. estimating bills, perimeter
