We have been putting our times table knowledge to the test and have been investigating patterns in squared and cubed numbers. Investigating factor and multiples through games and investigating patterns in prime numbers. As well as developing our mental recall through quick addition, doubling and halving.
Our hot questions for this week are - do you think you could answer them?
Draw a rectilinear shape on squared paper with a perimeter of 50cm. How many other rectilinear shapes can you draw with a perimeter of 50cm
A ‘perfect’ number is a number whose factors (other than itself) add up to itself, e.g. 6 6 = 3 + 2 + 1 There is one perfect number less than 100. What is it?
Choose a prime number greater than 3. Square it, then subtract 4, then divide the new result by 12 and record the remainder. What do you notice? Why does this happen?
Explain why a number that ends in 3 cannot be a multiple of 4.
Write one number which fits all three of these statements. It is a multiple of 4. It is a multiple of 6. It ends in ‘8’.
We investigated how to calculate perimeter, how to calculate the lengths of a shape with only a given perimeter and have begun to investigate composite shapes and how to calculate their perimeter.
We investigated what symmetry was and what shapes it existed in. Some of us began to develop an undertstanding of reflective symmetry and some of use investigated patterns of symmetry in triangles.
Have a go at some of our hot question from this week:
We learned how to use a protractor to measure angles and some of us developed skills to help us draw angles. We developed knowledge of right, obtuse and acute angles and some of us had to find reflex angles, which was rather tricky!
We had a lot of hot questions which made us think this week, do you think you could solve them?
