Partition the 2nd number to add 10s then 1s including bridging

The ArithmeKit 3 5 from Buzzard Publishing, part of the CanDoMaths series, offers a range of mathematical exercises focusing on the addition strategy of partitioning the second number to add tens and then ones, including when bridging is required. Students are presented with tasks such as finding missing numbers in addition sequences and using a number line to validate their answers. For example, they learn to break down the number 151 into 100 and 50 when adding it to 348, resulting in a total of 499. This method is applied to a series of similar sums, encouraging students to notice patterns in their calculations.

The resource also includes matching pairs problems and challenges students to create their own. Pupils are encouraged to explore different methods of addition, such as the statement by a character named Colin who suggests that the best way to add 275 and 356 is to start with the larger number and add the hundreds, tens, and then the ones. The kit includes various problems that require students to fill in missing digits to make the statements true, using each digit from 0 to 9 exactly once. This reinforces their understanding of place value and addition while also providing an opportunity for problem-solving and critical thinking.
