Skip Counting Fives

Learning to match the fives with the numbers 1 to 12 is key to telling the time on an analogue cock. For our kid, this was the first introduction to a multiplication table – a mathematical tool useful in the context. But first, we spent a long time with the number pairs. In a set of five lessons on telling the time, we used ‘the fives’ in all of them, but only discussed multiplication; the \times symbol and the = symbol in lesson #4.

A set of Cards

To print: Multiples 5

In this task, print the numbers 1 – 12 on a different colour sheet from the multiples of 5.

1. Shuffle the cards together then scatter them face up on the floor. Make pairs, eg, it takes ‘3’ hands to count ’15’ fingers. etc.

2. Memory pairs. Nice to have the ‘answers’ visible somewhere in the room. We had this applet on a tablet with ‘minutes’ showing beside us.

3. Go fish (for pairs). Start with four cards each, up to three players. Again, nice to have the ‘answers’ to hand.


To print: Rectangles Rows of 5

1. We did a scavenger hunt. We gave each rectangle a name, made up a story about spying rectangle-aliens, wrote a list with ‘name & number of boxes’. When each rectangle was found it was identified by the number of boxes then its name was scored off the list.

2. Making rectangles:

Math Playground

In this game of snake you can choose 5’s only. Look for the calculations below the graphics. The snake will eat all seeds it passes and get longer for every seed, however only the answers to the calculations given add points. The game ends when the snake gets stuck. The shorter you keep the snake, the longer you last.

The Clock on the Wall

Finally, on our last lesson I cut out 12 arrows and wrote on the multiples of 5, mixed them up, put tape on the back. When my kid put them on the wall, she got to correct me for writing the numbers in the wrong direction. This was a nice self-correcting exercise for both of us! I expect that the rectangle aliens will probably return and remove these one by one from the wall, hopefully when they are no longer needed…
