We have been talking about the Royal Adelaide Show. We looked at the show website and how to make a show bag wish list. It was great to see what you could get in each bag. We saw how much the bags cost and what the real value of the bags were. Some bags cost $25 but were worth between $60 and $85 so they were great value for money if they were something we wanted.
In Mathematics we have been learning about 3D shapes and the difference between 2D and 3D shapes. 3D shapes have the extra dimension of ‘depth,’ while a 2D shape is a flat shape. A cube is a 3D shape and has 6 square faces. We made these “Jack in the Box’ cubes from the net of a cube. Some of our ‘Jack in the Boxes’ have footballs coming out of a box designed with football pictures and others have fish coming from underwater scenes. We had fun learning about cubes. Which views are side views? Can you find a photo that is a ‘top down view’ or ‘bird’s eye view?’

In Mathematics we have been working on problem solving tasks. This work is more challenging because it means the children have to apply previously learned knowledge in new and varied situations so it requires some more advanced thinking. It also involves some representations diagrammatically and good organisation to help with accurate counting
In Mathematics the children have been learning about time – the duration of a minute/hour/day/year. Some of this has involved measuring what you can do in a second and compared to a minute or hour. Morning and afternoon and how it is divided by the mid-day and noon time has been discussed and events divided into morning and afternoon (events such as getting up, going to bed, going to school and having dinner).
Some mathematics work this week has centred around different number combinations with the numbers 7,8 9 and 10 and number line work. The children were also asked to try their own number lines which could go forward, backward, diagonally and from different starting points. The connection was made between number lines and History Timelines. In Time different activities were matched to different times and number fluency (no aids) from 1-100 was checked.
Some great Sharing ideas using time measurement. How long does a minute take, or an hour or a season or a year?

In Mathematics we have been learning about patterns – they are evident in number work, spatial and algebraic maths. This video helps the children visualise how big numbers ‘grow’ with multiples of 10.
We played the Tens and Ones game with a partner. We had to take turns and after we had ten Ones in the Ones column we had to bundle it into a group of ten. At the end of the game we had to add our Tens and Ones to find our score and see who had the highest number.
In mathematics we are consolidating the concept that numbers under 100 are made up of tens and ones. ‘Teen’ numbers can be problematic with reversals (such as 17 being written as 71) sometimes happening when there is no learning issue – just that it’s tricky to remember which numeral comes first. We use this Rap to help us remember.
