Problem solving with addition and subtraction worksheet

The worksheet presents a series of engaging activities for KS2 students to practice problem-solving with addition and subtraction. Activity 1 involves a 3 x 3 grid and a set of digit cards with odd numbers ranging from 1 to 17. Students are tasked with arranging these digit cards within the grid so that the sum of the numbers in each row, column, and diagonal is equal, with the solution resulting in a total of 27 for each. This activity encourages children to think critically about number placement and the relationships between numbers to achieve a balanced grid.

Activity 2 takes a different approach by providing a grid and a smaller set of digit cards numbered 1 to 4. Students must place the numbers on the grid in such a way that the difference between any two connected boxes is greater than 1. There are two possible solutions provided, demonstrating the importance of exploring different combinations. Subsequent activities continue to challenge students' understanding of number facts and arithmetic operations. Activity 3 asks students to find all possible combinations of the numbers 1 to 8 that add up to 13, with six solutions in total. Activity 4 pushes students to use digit cards 0-9 to find the highest and lowest possible sums in a given format. Finally, Activity 5 uses whiteboards and pens for a practical exercise where students determine what must be added or subtracted from one 3-digit number to transform it into another, enhancing their mental calculation skills and understanding of place value.
