Know number facts in Year 2

A lot is expected of children in Year 2, especially what they should know off by heart when calculating. By the end of the year they should:

•    know all addition facts for two numbers up to a total of 10.      (eg 4 + 5.)

•    be able to derive subtraction facts for numbers up to 10.     (eg if they know that 6 + 3 = 9, they can instantly work out that 9 – 6 = 3.)

•    know all the pairs of whole numbers which total 20.    (eg 16 + 4.)

•    know all the pairs of multiples of 10 which total 100.   (eg 30 + 70.)

•    know the doubles of whole numbers up to a total of 20.  (eg double 7.)

•    understand that halving is the inverse of doubling and hence derive halving facts from their knowledge of   doubling.   (eg if double 8 is 16, then half 16 is 8.)

•    recall 2, 5 and 10 times-tables.  (eg know 5 x 6.)

•    work out related division facts.   (eg if 5 times 2 is 10, then 10 divided by 5 is 2.)

Now, that is quite a lot to know with instant recall, and they will need plenty of practice to achieve this. Why not go to our Year 2 Knowing and Using Number facts to help them on their way?

Maths puzzle: Year 4 Handling data wordsnake

The Primary Framework for Mathematics has given each year group a set of mathematical words that they should know. This word snake contains words from the data handling section of year 4. There are only 8 of them but every letter in the grid is used once.

The words can be found by moving across or up and down (but not diagonally). The next word follows on directly from the first.

The first word (survey) is given to you so that you can get the idea. The first letter of next two words is also given, then you are left to find them with no help.

This is not easy: try it yourself. A great way to use some of the necessary language in a fun way.

This page can be found in our Maths Puzzles category.

Maths game: Three hexagon

Playing board games and card games from an early age is a great way to help children with their maths. Whether it is matching pairs, counting on or back or throwing dice, the participation involves calculating skills, predicting, seeing patterns and thinking logically.

Here we have a great little maths game for young children, thanks to MathSphere from its CD, ‘It’s All Figured Out!’

The rules are as follows:

This is a game for two people.

Each player has three counters.

The aim of the game is to get the three counters in a straight line.

The player going first places a counter on one of the circles.

The second player then places one of his/her counters on a circle. This continues until all the counters have been placed.

If neither player has got 3 counters in a straight line then the first player slides a counter along a line to a circle that is not already covered.

The other player then slides a counter to an adjacent circle.  Counters can only move along one line into an empty space. They can not jump over counters.

If a player can not move a counter she/he misses a go.

Is there an advantage in going first? By careful placement of the counters at the start of the game can you ensure that you will always win?
