Year 5 Block B – Securing number facts, understanding shape
The focuses of mathematics learning within this block are:
 Written methods: addition and subtraction of decimals
 Mental methods and recall: sums, differences, doubles and halves of decimals
 Tables to 10 × 10; multiplying/ dividing multiples of 10 or 100
 Factors, common multiples
 Patterns, relationships and properties of numbers and shapes
 Representing a problem using calculations or diagrams
 Visualising 3D and 2D shapes
 Properties of 3D and 2D shapes
 Nets of solids
The objectives for the block are listed in the table – the right hand column indicates how the objectives might be addressed in the units
Objectives  Unit 1  Unit 2  Unit 3 
Explore patterns, properties and relationships and propose a general statement involving numbers or shapes; identify examples for which the statement is true or false 



Represent a puzzle or problem by identifying and recording the information or calculations needed to solve it; find possible solutions and confirm them in the context of the problem 



Use knowledge of place value and addition and subtraction of twodigit numbers to derive sums and differences and doubles and halves of decimals (e.g. 6.5 ± 2.7, half of 5.6, double 0.34) 



Recall quickly multiplication facts up to 10 × 10 and use them to multiply pairs of multiples of 10 and 100; derive quickly corresponding division facts 



Identify pairs of factors of twodigit whole numbers and find common multiples (e.g. for 6 and 9) 



Use knowledge of rounding, place value, number facts and inverse operations to estimate and check calculations 



Use efficient written methods to add and subtract whole numbers and decimals with up to two places 



Use a calculator to solve problems, including those involving decimals or fractions (e.g. to find ^{3}/_{4} of 150g); interpret the display correctly in the context of measurement 



Identify, visualise and describe properties of rectangles, triangles, regular polygons and 3D solids; use knowledge of properties to draw 2D shapes and identify and draw nets of 3D shapes 



Complete patterns with up to two lines of symmetry; draw the position of a shape after a reflection or translation
