This week we are learning about 3D shapes. We have been revising our knowledge of their names and are continuing to build on our existing knowledge of their properties. Activity The children played a shape game today and they really enjoyed it. Here is how to play:
How you can help...
One of the hardest things for children to remember about 3D shapes is their properties. This is often because they cannot visualise the shape. To help with this try and find things around the house for each shape. For example, a pack of pringles is the shape of a cylinder, a packet of cereal is a cuboid, a dice is a cube, etc. When they are asked about the features of the shapes they can then picture each item in their house and think about their properties a lot easier. 3D shapes that we are covering Sphere, cylinder, cube, cuboid, cone, triangular based pyramid, square based pyramid, triangular prism 2D shapes that we are covering 2D shapes- circle, semi-circle, triangle, square, rectangle, pentagon, hexagon, heptagon and octagon. Tricks Triangle- a tricycle has three wheels. Semi- means half so half a circle. Pentagon- a regular pentagon looks like the nib of a pen. Hexagon- has the x sound as does the number six so it has six sides and six corners. Octagon- octopuses have eight tentacles so octagons have 8 sides and 8 corners. For maths homework this week the children have been asked to complete a revision sheet from Block A of the Numeracy Framework. This unit involves the number system.
1.) 87-64 Solution: On the number line start with 87 on the right side then take away sixty then four. 2.) What number is 25 less than 67? Solution: 67 - 25 = 3.) 37 + 94 = Solution: On a number line the children start on 94 and add on 3 tens then 7 units. 4.) Write different ways of making 65. 5.) 57+___=97 69+___=109 79+___=199 Solution: find the difference between these numbers using number lines. Put 57 at one end of the number line and 97 at the other. Then add on from 57 to This week we have been looking at 'halfway' and rounding. Finding numbers that are halfway between two lots of numbers Method Question: What number is halfway between 63 and 103? Step One: Find the difference between 63 and 103 by counting on in tens from 63 to 103. Step Two: Divide the difference by 2 (half) Step Three: Add this number to the original. Example Step One: 63 + 40 = 103 Step Two: 40 divided by 2= 20 Step Three: 63 + 20 = 83 Halfway between 63 and 103= 83 Rounding numbers to the nearest lot of ten Method Question: Round 63 to the nearest lot of ten Step One: What lots of ten are either side of 63? Step Two: What is halfway between 60 and 70? Step Three: Is 63 less than, equal to or more than 65? Step Four: Round to the lower lot of ten. Example Step One: 60 and 70 (draw a number line to help if necessary) Step Two: 65 is halfway between 60 and 70 Step Three: 63 is less than 65. Step Four: 63 is closer to 60 than 70. The nearest lot of ten to 63=60 This can all be plotted on a number line to help. See the picture Happy New Year!
In Numeracy this week we will be consolidating and extending our knowledge of reading and writing numbers up to three digits. We will also been looking at three digit numbers and identifying what each digit is worth. This will be built on by investigating the use of all four operations (addition, subtraction, multiplication and division) to find totals up to one hundred. Towards the end of the week we will be moving onto consolidating and extending our knowledge of odd and even numbers. As an introduction to division and multiplication, we are learning about halving and doubling numbers. The students are currently being taught about the relationship between the two; they are inverse operations.
Example: Double 18=36 So, half of 36=18 We will be building on this by acknowledging that doubling is the same as multiplying numbers by two and halving is dividing numbers by two. By the end of the work week the children will be finding halves and quarters of shapes. What have we been learning? This week in maths, we have been learning about time. More specifically, we have been studying analogue clocks. Time is very tricky for children to learn so refreshing their skills regularly is extremely useful. Vocabulary Half past, quarter past, quarter to, o'clock, small hand, big hand, past, to. Skills Counting in intervals of five; recognising that the hour hands as well as the minute hand; understanding that when the minute hand is on half past, the hour hand is halfway between the relevant hours; reading digital clocks; converting the 24 hour clock into a.m. and p.m.; and duration.

Miss WrightWelcome to our maths page! This is where I will update you on the work we are covering in class each week. There will be a selection of website links available to support you with homework. Each week I will post a selection of photographs so you can see how hard the children have been working! Enjoy!
