brother/sister
farmer
pilot
judge
librarian
factory worker
Why? Why not?

1. Square Lashing
This is useful for attaching sticks together to make mobiles, swords, frames, stars and so on.
2. Clove Hitch
Use this knot to attach a rope to a fixed post to make a washing line or similar. Use this knot to start a square lashing or simply to attach some string to a stick for mobiles, story sticks, fishing rods and so on.
3. Reef Knot
This knot is for tying two ends of a line together and it holds tight for example to give you a longer length of rope.

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?

Published 10/07/20, by Charlie MackinnonWell done Ryan. I love the way you have made the smallest and largest possible numbers using the digits and each place value grid.

Published 09/07/20, by Charlie MackinnonWrite 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 number. e.g. 6.94
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 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 numbers?

What are more useful, letters or numbers?
Would it be a good thing if animals could talk?
What is braver- being scared of something and then doing it anyway or not being scared in the first place?

Published 07/07/20, by Charlie MackinnonMake 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. Use the marked cup to keep track of rotations. Experiment by changing the height and speed of the flow of water. What difference does a faster flow make?

Two children are playing with three balls, one blue, one red and one green.
They toss up the balls, which run down a slope so that they land in a row of three.
In how many different ways could the balls land?
Can you use and apply a systematic way of working to ensure that you find all the possible solutions?
If you want to explore this challenge using an interactive activity, please follow this link.
Extension: What would happen if you added a Yellow ball as well?
Would this increase or decrease the number of possible ball arrangements? Prove it!
