2) B because numbers with three decimals places can sometimes be larger than those with two decimal places and they can sometimes be smaller. Here are some examples:

Smaller

2.154 < 7.81

0.504 < 0.54

Larger

2.154 > 2.15

0.504 > 0.48

3) D because, whilst A shows regular partitioning, both B and C have values equivalent to 8.36 too.

2) B because we are rounding to the nearest tenth and, for this, we need to look at the hundredths column. We have 6 hundredths which means we need to round our tenths up.

3) A because we are rounding to the nearest integer and, for this, we need to look at the tenths column. We have 0 hundredths which means we need to round our integer down.

Here's a game where you can test your skill at putting small numbers into the right order - it's not as easy as it sounds!
 

How to play

You need a partner, a copy of the game board, and two different coloured pencils.

Decide who goes first.

Take turns to choose a number from the grid and mark it on the spiral. Make sure you know where 0 and where 1 is!

Keep taking turns until one of you has marked three numbers next to each other.
