Counting by tens up to 100

In this video, we will learn how to count in multiples of 10 up to 100. The numbers in the 100 square with a pink box around them are all multiples of 10. Let’s practice counting in tens up to 100. 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. Did you notice that all of these numbers end in a zero? Let’s practice counting in tens using some example questions.

Hannah put these toys into groups of 10. How many toys are there? 40, 10, or 30.

Hannah has started to count in tens — 10, 20, 30. What comes next? 10, 20, 30, 40. If Hannah puts her toys into groups of 10 and there are four groups of 10, she has 40 toys. 10, 20, 30, 40.

There are 10 bowling balls in each group. How many bowling balls are there? 50, five, or 40.

To find out how many bowling balls there are altogether, we need to count in tens. This is because the bowling balls have been grouped into tens. Let’s count in tens — 10, 20, 30, 40, 50. Five tens are 50. There are 50 bowling balls altogether.

Which number is missing? 50, 60, 70, 80, what. Is the missing number 90, 80, 100, 70, or 60?

In this question, we start counting at number 50. And we’re counting forward in tens — 50, 60, 70, 80. What comes next? The missing number is 90. 50, 60, 70, 80, 90. The missing number is 90.

What have we learned in this video? We’ve learned how to count in multiples of 10 up to 100. 10, 20, 30, 40, 50, 60, 70, 80, 90, 100.
