Planning a Unit in mathematics

Unit: Year 3 Block B3 - Securing number facts, understanding shape

Lessons: 15

Learning objectives - Most children will learn to:

1.

Solve one-step and two-step problems involving numbers, money or measures, including time, choosing and carrying out appropriate calculations

2.

Represent the information in a puzzle or problem using numbers, images or diagrams; use these to find a solution and present it in context, where appropriate using .p notation or units of measure

3.

Identify patterns and relationships involving numbers or shapes, and use these to solve problems

4.

Read and write proper fractions (e.g., ), interpreting the denominator as the parts of a whole and the numerator as the number of parts; identify and estimate fractions of shapes; use diagrams to compare fractions and establish equivalents

5.

Derive and recall all addition and subtraction facts for each number to 20, sums and differences of multiples of 10 and number pairs that total 100

6.

Derive and recall multiplication facts for the 2, 3, 4, 5, 6 and 10 times-tables and the corresponding division facts; recognise multiples of 2, 5 or 10 up to 1000

7.

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

8.

Relate 2-D shapes and 3-D solids to drawings of them; describe, visualise, classify, draw and make the shapes

9.

Use a set-square to draw right angles and to identify right angles in 2-D shapes; compare angles with a right angle; recognise that a straight line is equivalent to two right angles

10.

Develop and use specific vocabulary in different contexts

add, subtract, multiply, divide, group, sum, total, difference, plus, minus, double, halve, multiple, product

Building on previous learning

Check that children can already:

Children's targets

1.

I can solve a problem by writing down what calculation I should do

2.

I can draw a picture to help make sense of a problem

3.

I can find numbers or shapes that match a property

4.

I can say what fraction of a shape is shaded

5.

I know and use all addition and subtraction facts to 20. I can find what to add to a number to make 100

6.

I know the 2, 3, 4, 5, 6 and 10 times-tables and use them for division. I recognise multiples of 2, 5 and 10

7.

I can estimate and check my calculations

8.

I can describe the properties of shapes. I can sort shapes using different properties

9.

I can say whether the angles of a 2-D shape are right angles or whether they are smaller or bigger

10.

I can picture a shape in my head when it is described to me. I can describe a shape so that others can draw it
