Addition and subtraction within 10 - Breaking apart - Worksheet

The 'Subtraction - Breaking Apart' worksheet is a valuable resource for helping Year 6 students master addition and subtraction within 10. The worksheet is aligned with the National Curriculum objectives, which include adding and subtracting one-digit and two-digit numbers up to 20, understanding number bonds and related subtraction facts within 20, and solving problems that involve addition and subtraction, including missing number problems. To facilitate the learning process, resources such as differentiated worksheets, teaching slides, and practical tools like part whole models, cubes, and counters are provided. The key vocabulary for this topic includes terms like add, subtract, number bonds, counting on, missing parts, part-whole, value, number sentence, partitioning, and break apart.

Students are encouraged to use the subtraction symbol and apply their knowledge of number parts to subtraction by partitioning numbers. They use concrete and pictorial representations to understand how to break apart numbers into two parts. The worksheet includes various exercises where students line up images as arrays and write number sentences. They also have to rely on their counting skills to find totals and complete their own number sentences. For those working at greater depth, the worksheet challenges them to partition numbers in multiple ways and solve more complex reasoning questions. The worksheet concludes with a section on reasoning and problem-solving, where students must think of questions to ask about given images, represent their questions and answers using part-whole models and number sentences, and explain their reasoning.
