This week we are looking at ways to re-use plastic bottles in maths play. I took four 1 litre sized water bottles and cut a simple hole near the bottom of each, leaving a little lip so that pom poms wouldn’t fall out when dropped in. Then I painted a thin band of colour around each one, using acrylic paint which adheres well to plastic. You could also just tie around a coloured pipe cleaner, or a strip of coloured paper.
Join us both every Friday for our continuing series about Playful Maths ideas.
