Lesson 1

LI: To add numbers mentally, including a three-digit number and tens

Recap last week’s lesson adding a one digit number to a three digit number.

Recap place value in a 3 digit number – Hundreds, tens and ones

Explain that as we are adding tens our ones column will not change.

Demonstrate how to add ten and multiples of ten to a three digit number

320 + 10 = 330

470 + 10 = 480

652 + 10 = 662

743 + 10 = 753

214 + 30 = 244

138 + 60 = 198

Explain what happens if we have more than 10 tens in the tens column – we need to exchange for a 100.

Go through some together to familiarise them before sending them to task

Lesson 2

Show your child the  sum 37 + 44 =

Ask your child how could you write this so that it is set out on top of each other in column addition.

Show your child how to correct set it out;

37

+ 44

____

Explain that it is important that we set out our questions correctly with the numbers in the correct column.

Work through a variety of 2digit + 2digit and 3digit questions with your child until they feel confident to work independently.

Lesson 4

L.I. Estimate and name angles

Recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn

### Tell your child today they will be thinking about angles, and in particular, right angles. What is a right angle?

Discuss how an angle is a measure of the arc or turn between two lines. Draw two lines that meet in a corner (not 90°) on the whiteboard and draw an arc between these lines. Tell children this is the angle. The word angle comes from the Latin word angulus, which means corner. So an angle is like the measure of how big a corner is.

• Discuss the fact that a right angle is what is known as a ‘perfect corner’. Show a right angle measure (i.e. a set-square). Show the right angle. It is ninety degrees.

Hold up a circular protractor or show picture

Explain this is a protractor used for measuring angles. We measure angles in degrees. There are three hundred and sixty degrees in a full circle  a complete turn. A right angle is ninety degrees, this is a quarter turn. Show on the protractor. Show on a clock face that a quarter turn from 12 to 3 is a 90° angle. Two right angles make a half turn, three right angles make a three-quarter turn, and four angles make a complete turn — three hundred and sixty degrees. Show on the protractor.

Activity

• Children find different things in a room which has a right angle.
• Draw a right angle and label it
• Draw a picture which has right angles

Lesson 5

L.I. Round numbers to the nearest 100

Model how to round to the nearest 100.  Draw a number line to help children understand.

If the t and u is 50 or more we round up, if it is less than 50 we round down.
