Year 5 absolutely powered through there fractions work, they made light work of multiplying fractions. Last week they looked at unit fractions (fractions that have 1 as the numerator) and this week they looked at non-unit fractions.
The whole class could see clearly that a simplified way of completing these multiplication questions was to multiply the numerator with the number stated:
For example, 1/4 x 3 is also the same us 3 lots of 1/4, which you can do as 3×1. So, the answer is 3/4. Last week they had also seen that it can also be done as a repeated addition of 1/4 + 1/4 + 1/4, which again is 3/4. This is a good way to check answers.
Year 5 looked at perimeter today. They showed they understood how to calculate the perimeter of a shape.
It was important to remember metacognition – thinking about what they already knew. It was important to remember the properties of shapes: knowing that rectangles have two equal, opposite sides. This information helped when calculating the perimeter of a shape quickly.
Have a look at Tanatswa’s work:
One of the challenges was to draw a rectangle which had a given perimeter of 14cm. This was a challenge in that they had to visualise the shape and understand that each of two sides had to have the same length.
The class had some time today to sharpen their skills on Ed Shed and TTRS.
It was easy to see who has been practising at home.
It is important that we practise everyday so that we can complete our Year 5 and 6 words, as well as be quicker with out times tables. We know that confidence with our spellings helps us as writers and readers. Confidence with our times tables helps us with everything in maths, which is so important.
Today Year 5 were investigating cubes and cubed numbers.
They looked at making a square with 6 cubes….it was impossible (no matter how much they tried). They added 3 more cubes, so that they had 9 cubes, and tried again. They definitely made a square with 9 cubes.
They continued with more cubes and then went on to investigate cubes, seeing that they were 3D shapes and that they needed the same number of square across, up and along.
So adding to our numbers which are square numbers, we now know what cubed numbers look like.
Today Year 5 looked at the relationship between numbers. They manipulated dienes to make numbers, add on and take away. This helped concrete the concepts of how many ones are in ten, how many ones and tens are in a hundred and how many ones, tens and hundreds are in a thousand.
The children then looked at adding and subtracting numbers and could see that if they added ones they may need to exchange for a ten or exchange tens for a hundred and so on.
Year 5 have been learning the properties of 2D and 3D shapes. They have been disgusting the properties of polygons and equilateral s and have been constructing nets to replicate 3D shapes, such as cuboid and rectangular prisms. It’s been good fun and they have learnt a lot.
