Negative numbers in context worksheet

Activity 1 offers a dynamic and engaging way for children to practice counting backwards with negative numbers. This activity requires no materials and can be conducted in a classroom, hall, or outdoor setting. The teacher begins by announcing a starting number and selecting the first child to count backwards from that number. As the game progresses, any child who makes a mistake must sit down, and the rest continue the countdown. The challenge continues until no children are left standing. To add an element of fun and unpredictability, the teacher can introduce 'Switch' commands, which reverse the counting order, or set a timer to record how long the group can go without errors.

In Activity 2, children are introduced to the concept of positive and negative movements on a number line through a hands-on approach. They will need a whiteboard and pens or a blank number line, along with a pair of dice and a counter for each participant. The number line should be marked from -10 to 10. Each child takes turns rolling the dice and assigns one die to represent a positive jump and the other a negative jump, starting from zero. The objective is to navigate back to zero using these positive and negative jumps. This activity not only teaches children about negative numbers but also involves strategic thinking as they decide which die to allocate as positive or negative.

Activity 3 encourages pairs of children to delve deeper into the world of negative numbers using whiteboards and pens or blank number lines, alongside a set of digit cards ranging from 0 to 9. Each pair receives four digit cards and is tasked with using them in conjunction with any mathematical operations to achieve a result of zero. This activity challenges students to think critically about the operations they choose and to calculate effectively to get as close to zero as possible. It's an excellent way to reinforce the understanding of negative numbers in a context that requires calculation across zero.
