## Year 4 maths worksheet: multiplying by 10 and 100

Understanding what happens when you multiply a whole number by 10 is crucial to understanding maths at primary school and indeed with later maths. Children should have carried out lots of practical work with base 10 apparatus in school to show that:

when you multiply a whole number by 10 the digits move one place to the left.

Now this may give the appearance of ‘adding a nought’ as a zero is placed in the units. I know of many teachers and publishers who still use this expression, but it is extremely dangerous, especially when it comes to multiplying decimals by 10. (0.8 is not 0.80).

Multiplying by 100 is the same as multiplying by 10 and then multiplying by 10 again (10 x 10 = 100) so each digit will move two places to the left and zeros will need to be placed in the units and tens.

When you multiply a whole number by 100 the digits move two places to the left.

## Maths vocabulary puzzle: ordering and place value

Here is a little word search to help children recognise and use the vocabulary expected of them in Year 1 to do with ordering and place value.

The words are:

more, less, plus, double, altogether, subtract, take, minus, half, difference and equals.

This is quite a difficult set of terms for children of this age (5/6 years old).

All the words on the wordsearch are either straight across or straight down – no diagonals.

It’s a while since we had a number puzzle so here is one to do with the two times table. This should encourage children with writing answers in words to the two times table that they find within the wordsearch. Not quite as easy as it looks as words such as eighteen and twenty are quite tricky to spell.
