1 Use a place-value chart
Put 4 in the tens column and 6 in the ones column. Four tens are worth 40.
4 tens and 6 ones = 46Place Value • Primary Maths
The digits in 46 tell us how many tens and ones it has. You can split the number in more than one way without changing its value.

How can you build the same number?
Put 4 in the tens column and 6 in the ones column. Four tens are worth 40.
4 tens and 6 ones = 46Write the value of each digit, then add the parts. The 4 stands for 40 because it is in the tens place.
46 = 40 + 6Swap one ten for ten ones. You now have 3 tens and 16 ones. Nothing has been added or taken away.
30 + 16 = 46Your turn
Choose a method. Work it out on paper or with objects, then check below.
6 tens and 2 ones — 60 + 2 = 62.
26 — Two tens are 20; 20 + 26 = 46.
Ask, “Could we make 46 with only three tens?” Let your learner exchange a bundle of ten for ten loose counters.
The digit 4 is worth 40 here, not 4. A digit’s position tells you its value.
Bundle ten objects, then add a few loose ones. Start with numbers between 11 and 19.
