Week 28 (Year 1 Block B Unit 3 Week 2) Maths activities from urbrainy.com

This week we are aiming to:

1. Explore nets of simple 3D shapes

2. Count on in 2s, 3s, 5s and 10s on a 100 square

3. Continue investigating simple shape patterns

4. Complete subtraction number sentences

5. Count up in halves

6. Challenge: 9 tile shape investigation

BRAIN BUILDING ACTIVITIES

This week we have some ideas to help brain building with shape.

1. Nets of 3D shapes

BRAIN TRAINING MENTAL ACTIVITIES

Try asking your children these sets of mental arithmetic questions during the week which concentrate on:

Set 1 and 2: more than, counting on, doubling/halving and addition

Sets 3 and 4: less than, counting back, subtraction and shape

BRAIN TRAINING PRINTOUTS

Settle down in a quiet corner with pencils and paper to have a go at these printouts:

1. Counting in tens on a number line

2. Count in 2s, 3s, 5s and 10s on a number square

3. Recognise shape patterns

4. Subtraction sentences

5. Counting in halves

6. Challenge: 9 tiles

MATHS SUPPORT: YEAR 1 (5-6 yrs old) WEEK 28 ACTIVITIES


The nets of 3D shapes

Most boxes, such as cereal boxes, are made of just one piece of card. There is usually very little glue involved and they can be opened out quite

easily to show the ‘net’ as it is called.

One of the simplest nets is the cube, which looks rather like a cross, although there are several other ways of making a net for a cube.

Collect together a selection of boxes and open them out. Ask your child to imagine the original box. What shape will it be when put back together? What shape will the ends be? How many faces will it have? (A good

excuse to buy a bar of Toblerone!)

Let your child trace round each of the sides of a box onto a large piece of paper, with edges touching so that the net can be made. Cut it out and see if it makes the box.

Let your child study a made up box and then see if they can draw what they think the net will be. This is hard! Unfold the box to see how close their net is to the original.

BRAIN BUILDING ACTIVITIES: WEEK 28

We are all getting used to recycling our paper and card nowadays and this involves much flattening of boxes to get them into the wheelie bins! However, these boxes are full of interest and before throwing away can provide a wealth of maths.

Challenge: 9 tiles

I’ve got 9 tiles. 3 red, 3 blue and 3 yellow.

I put them together to make a square, but I’m not allowed to put two tiles the same colour next to each other.

How many ways can you find to do it? Record your results.

Cut the tiles out, rearrange them and then draw your results on the paper.
