Are you looking for an activity for your students to practise solving problems using addition and subtraction? This activity allows your students to practise their additive strategies by keeping track of the number of passengers getting on and off a bus.Students select a card of each colour to add to each bus stop, adding or subtracting as they go. Finally, they must find the solution card to match for the final stop. This download includes play mats with up to four ten frames, allowing you to differentiate for your extension learners easily with more challenging sums.This resource works well independently, with small groups or for modelling additive strategies to your whole class.Print this activity and slip it into a write-and-wipe sleeve so your students can use the ten frames by drawing dots with a whiteboard marker. Alternatively, enlarge your print to A3 and use small manipulatives!A black and white printing option is also included that uses stop numbers instead of colours.Looking for more resources to support your students in learning to solve practical problems involving additive situations?
