About this resource
Break three-digit numbers into hundreds, tens, and ones using a worked model and labelled response spaces. Ten practice prompts include numbers with zero tens, encouraging students to attend to every position. Recombining the parts after each response provides a way to check the original numeral.
Curriculum reference — Ontario: Three-digit decomposition is the actual task; source Grade 1 tags are not authoritative. The three-digit place-value task is within Ontario Grade3 representation to1000. The supplied hundreds/tens/ones task matches England Year3 place value. Selected skills only; reference stage is not an overall reading age, complete curriculum coverage, or an automatic recommendation for every learner.
