Times and divide as inverse operations

Today we explored multiplication and division as opposites.

Give children 3 numbers - they can use the numbers to make two multiplication sums
                                                                                             and two division sums

Inverse game


You can give your child 3 numbers (multiples of 2,3,4,5 only) and see if they can come up with the 4 sums.

This is what we have been doing in class:








Rounding to the nearest 100

 Start with a 3 digit number...

346

1) What two hundreds does it lie between?
2) Which hundred is it closest to? Would be round up or down?

To answer the second question, I have encouraged the children to look at the tens column. If it is less than 50 round down, or 50 or above, round up.

It is also good to draw it out and make a blank number line, so it is very visual for them.
If they do this, they should find the number that lies half way between them and mark it on the number line. They may also want to mark on the tens. Then they can clearly see whether it is above or below and so know which way to round.

Measuring length

Rulers and tape measures have been out this week!

The children have been estimating, measuring and recording length to the nearest half cm.

We have briefly looked at mm, but the children don't need to worry about being too accurate yet - reading to the nearest half cm is fine for now.
Of course, if appropriate, you could have a go!

When recording halves, the children should use .5, they should know this is because it is 5 little mm along.

Next week...

Number bonds to 100!

Starting by recapping our number bonds to 10

Adding and subtracting 10p!

We've been both cutting and increasing prices today - involving adding and subtracting multiples of 10.

i.e. £2.10 + 10p = 

      £3.45 - 10p =

      £2.25 + 30p =

      £4.48 - 30p =


To make this easier, I have encouraged the children to write HTU (hundreds, tens, units) above the appropriate digit first. This way they can identify what the tens number is, as this is the only number that will change.


It is a good idea to always begin with adding and subtracting just 10p, and then progress to other multiples of 10.

You can have a go at pricing a few items at home and setting up a shop. Slash prices for the day or put them up as a way to raise some extra money for charity!






We have also talked about the importance of using zero as a place holder, when there are no tens.
i.e. writing £5.08 instead of £5.8

Money

Today we started to look at money, and will be focusing on this next week.


The children will be learning to:

*Identify the names of all the coins (1p, 2p, 5p, 10p, 20p, 50p, £1, £2) and use them to make varying amounts. 

*Read and record amounts of money using £ and p, including use of zero i.e. £3·05

*Use place value to solve problems and add and subtract amounts of money


Here are some great games, if you would like to have a go with your child:


Sort, count and order
Giving change - subtracting
Igloo shopping
Shopping bag
Pay using 1 coin

Fractions

We have been exploring fractions this week - helping the children to understand fractions as parts of wholes.

The fraction wall helps with this





The children should realise that each part must be equal, and the bigger the 'number at the bottom', the smaller the part is.
You can ask questions like... 'which is bigger, 1/2 or 2/6?' etc. They can use the wall to help.


These are great games the children really like:



We have also been finding fractions of given amounts too. The children will need counters or cubes or coins, something they can split up.

Can you find:
1/2 of  16   (they should know this by heart)
1/3 of 15
1/4 of 20   etc.
Try 2/3 3/4 etc. when confident 

Try this...  Would you rather?
