During this half term, we have mostly looked at place value and addition and subtraction. It is really important that children understand how the number system works and how to make 10. We learnt a song to help us with number bonds to 10, to the tune of 'Row, row, row your boat':
9 and 1 are number bonds,
8 and 2 are friends,
7 and 3,
6 and 4,
5 and 5 are twins!
When we look at 2-digit numbers we have been learning to identify how many ones and how many tens the numbers have. We know that the number 24 is made of 2 tens and 4 ones; the number 24 is the same as 20+4.
We have also been using our knowledge of number bonds to help us with addition that bridges the 10s boundary.
When adding a 1-digit number, we first partition the number to create a new complete ten. In 17+5, we partition the 5, using 3 to add to 17 to create a complete ten (20), which then leaves 2 of the next ten. Therefore 17+3 = 20+2 = 22
We have also used number lines to support children with addition and subtraction. Children have been working on remembering to make their first jump along the number line when they say 'one' - a common error is to count the number they are starting from!
We have been using place value grids to help us use equipment when making and adding 2-digit numbers.
We used it first when our numbers didn’t bridge ten.
We also have begun using equipment and place value charts to add numbers which create a new ten - which we then move into the tens column. We found them really helpful.
We have done lots of multiplication and division this half term. We have used equipment, arrays and learnt some facts.
We wanted to share one of the songs we sing in class to help us.
To finish our unit on statistics, we wanted to find out which crisp flavour was the favourite in our class. We began by mindfully tasting each flavour by leaving it one our tongue and closing our eyes to focus on the flavour we could taste.
Then we voted for our favourite flavour and tallied the results.
We used the skills we have learnt over the last two weeks to help us create a bar diagram showing the results and answered questions interpreting the data.
