Get your students making â€˜Friends of 20â€™ with this activity! Students will be required to perform mental arithmetic (with the aid of concrete materials, such as counters and number lines if required) to determine three numbers that add up to twenty. Students are working with counting on strategies, even when working with three numbers. They count on to add the first two numbers together and then count on again to twenty.

This Friends of 20 activity has six game options â€“ three to play with a group, and three for students to play independently. Lots of scope for differentiation. You could use these activities as part of a week-long topic on addition where students are asked to compare, order and make collections to 20. Play a different game each day. Available at Project Nature-Ed's Designed by Teachers store.

Generate conversation about topics beyond straight maths (and not just keep the natural world in science)! Connect this activity with the natural world outside of the classroom by making ladybug counters.

Get your studentsâ€™ brains going with this Buzz Brains activity! Students will be required to perform mental arithmetic and apply knowledge of times tables to solve area and perimeter problems.
