Maths Support Week 1 Spring 2

divide grid

x grid

place value chart

After half term the children will be re-visiting dividing and multiplying by 10, 100 and 1000.
The children have used the place value chart to decide whether the numbers will move left or right and change their value, depending on whether they divide or multiply the number. They also use the chart to decide whether they move the numbers 1, 2 or 3 places.

Cryptography

This week, the children have been learning about cryptography. They have been trying out different semaphore messages to each other such as their names and greetings. The children also had a go at creating their own Ceasar Cipher messages to each other. They enjoyed creating a code and deciphering each other’s messages.

Maths Support Week 6

Next week the children will be looking at regular and irregular polygons. They will need to be able to talk about the properties of equilateral, isosceles, scalene and right angled triangles. They will also learn about different four sided shapes including a parallelogram, rhombus, kite, trapezium. We would like the children to be able to recognise parallel and perpendicular lines in shapes.
There is more information about all of these shapes on the following website;

Science Pulley Making

This term we have been looking at different forces (friction, air resistance and water resistance) and their uses in every day life. We thought it would be great for you guys to create yourself a simple pulley machine at home, to determine the different forces working together.

A simple fixed pulley is one which enables you to pull down while the load goes up. It requires the same force, but it is easier to pull down (i.e. in the same direction as gravity) than to pull up.

Make a Simple Pulley to Lift a Weight

Equipment: Wire coat -hanger, wire cutter, empty thread spool, string, cup-hook, board (fixed), weight (e.g. a book)

1. Cut the bottom of the coat-hanger in the middle (adult help needed) and insert the spool into the open ends of the wire. The severed ends of the wire in the coat-hanger activity can be sharp, so be careful when working with them, as well as with the wire cutter. Children should be closely supervised for this activity, and an adult may want to help with this step.

2.Adjust the wire so that the spool turns easily, and then bend the ends down to keep the wires from spreading.

3.One child holds the coat-hanger by the handle while the other child attaches the weight to the string and loops it over the spool.

4. Pull the string to lift the weight.

Good luck!
