Teaching Tens And Units Year 1. The concept of hundreds tens and ones is taught by simply grouping ones into a group of ten ones and then a hundred ones. Teach addition with a carrying in stages over a period of time.
In this lesson we refer to the units as red and the tens as blue. The children then understand the value of a number by its colour. Number 33 is 3 tens and 3 units etc.
Place value headings like tens and ones tells us about the value of a digit in a number.
You can change the colour to suit the needs of your classroom. When teaching hundreds tens and units it is important to introduce this topic using physical objects such as counters or base ten blocks. Watch the video to learn how to count with tens and ones. The idea is to teach children that things can be grouped into larger numbers to be more easily counted and organised.
