Skeleton Shapes

Skeleton shapes are made with balls of modelling clay and straws.

This shows a cube and a skeleton cube:

How many balls of modelling clay and how many straws does it take to make the cube?

Here are some piles of modelling clay balls and straws:

Look at the shapes below and decide which piles are needed to make a skeleton of each shape.

Extension: Can you make a skeleton shape out of modelling clay and straws?

Write each of these digits on a piece of paper and cut them out. 

Draw a place value grid that looks like this:

Place each digit card into a position on the place value grid to create a 3-digit number. e.g. 694

If you use all the digit cards, what is the smallest number you can make?

If you use all the digit cards, what is the largest number you can make?

Can you use a systematic method for working out ALL the possible 3- digit numbers you can make?

Can you arrange them from smallest to largest?

EXTENSION: What happens if you add another digit card- a 5 for example. Does this mean you can make more different 3-digit numbers?  

Well done Heera, we love this writing. 

Wow! Jessica, we love the range of different types of sentence you used. Also, the way you included well punctuated, direct speech was amazing. 

It sounded just like something Roald Dahl would write. 

Make a Water Wheel  

Equipment for 1 water wheel

2x sturdy paper plates

Ruler and pencil

Plastic tub

Length of dowel longer than the width of the tub

Scissors

Sticky tape

Recycled plastic cups, pots or paper cups

Permanent marker

Stapler

Jug or watering can

Water

To Make the Water Wheel 

1. Measure and mark the centre of the two paper plates.

2. Perforate the plates with a pencil at the marks.

3. Push the dowel through the two plates.

4. Staple a minimum of three cups snugly between the two plates.

5. The cups should be evenly spaced and all facing the same direction.

6. Mark one of the cups prominently with a permanent marker.

7. Balance the wheel width-ways across the tub.

Investigation

Steadily pour the water from a jug into the top cup of the water wheel and watch it begin to rotate as the water flows. Count how many rotations the wheel makes using 1 litre of water?

Make a Prediction

If you have more water, will the wheel turn more times? 

Prove it!
