Some Mad Minute Tips:

E.g. 4x is double 2x

8x is double 2x and double again

6x is double 3x

All multiples of even numbers are even numbers

9x the digits add to nine 27, 45 etc.

3x7 = 7x3

Ox anything = 0!

Use counting strategy from known fact 5x8 to find e.g 7x8 (40, 48, 56.)

The Net Challenge:

Our task was to design the buildings and layout of the first colony on Mars. Each building or structure needed to be designed as a net on graph paper, then transferred onto card to provide strength.

The three dimensional shapes we investigated this week:

- Cube

- Cuboid

- Cylinder

- Prism (Hexagonal, Triangular)

- Square-based Pyramid

- Triangular-based Pyramid

- Cone

- A Trapezoidal Prism

Here are the results of the Architectural Competition between the design groups. Each group was given a score out of ten for Collaboration and Team Work', 'Imaginative Design' and 'Quality and Accuracy of Net Construction'.
