Counting Tens and Ones up to
120.

In this video, we will learn how to
group objects into tens and ones to help us count them more easily. Let’s look at an example. Benjamin and Amelia are counting
the blue cubes. They know that ten ones make a
ten. Benjamin says, “There are two
tens. There are three ones left
over.” Amelia says, “There are 23
cubes.” Benjamin and Amelia have grouped
their blue cubes into two groups of ten. They can count these cubes in tens:
10, 20. There are three ones left over, so
we have 20, 21, 22, 23 cubes. The number line shows how we
counted the cubes: 10, 20, 21, 22, 23.

Let’s try another example. Now it is your turn.

Look at the orange cubes and
answer the questions. How many tens are there? How many ones are left? How many cubes are there in
total? There are four tens. Now let’s count how many ones
are left: one, two. Now let’s count how many cubes
there are in total. First we can count our four
groups of 10: 10, 20, 30, 40. We know we have two ones. 40 plus two makes the number of
cubes we have in total: 40, 41, 42. We can count our four tens and
two ones along a number line: 10, 20, 30, 40, 41, 42. There are four tens. There are two ones left
over. There are 42 cubes in
total.

In this video, we’ve learnt how to
group objects into tens and ones to help us count more easily.
