Explain that when you skip count in 5s you always count 5 more. Ask two students to come to the front and to hold out their hands. That way all students can clearly see their fingers. Count aloud in groups of 5, pointing at the students hands. You can also do this together with the students. Ask one of the students in class to raise one hand, and say '5'. The next student must raise a hand and say '10'. Continue asking students in class to raise their hands, saying the next number in sequence until you reach 50. The interactive whiteboard shows the numbers 1-50, and all the numbers for skip counting in 5s are blue. Explain that these are important numbers for skip counting in 5s. Next is a bead string with 45 beads you can count together as a class. You can also do this with 30 fingers. Encourage students to skip count in 5s. First count the groups, and then count the remaining objects.

To check that students can skip count in 5s to 50 you can ask the following questions:

- What's a useful way to count these big numbers?

- Why is it useful to skip count in 5s?

- If you have many groups of 5 and one loose object, which do you count first, and why?
