Place value - Comparing numbers within 50 - Starter

In a Year 2 mathematics lesson focused on place value and comparing numbers within 50, students begin with a starter activity that prompts them to assess whether shapes have been sorted correctly. This initial task sets the stage for a series of engaging and educational exercises. The children are then presented with simple addition problems such as '2 + 3' and are asked to perform calculations such as '3 4', which helps them to become more confident and fluent in basic arithmetic. 'Fluent in Four' is a revision segment where students complete sentences to show their understanding of number representation, reinforcing their grasp of place value.

Through a series of practical scenarios, students apply their counting skills to solve real-world problems. For instance, Tia has 8 blocks and adds 7 more, and the children must calculate the new total. Another problem introduces the concept of subtraction, where 4 blocks are added but 3 fall down, and students must determine the remaining number of blocks. This hands-on approach helps to solidify their understanding of addition and subtraction within the context of place value. Additionally, the lesson includes an exercise where students must verify if a set of shapes, such as cubes and pyramids, have been sorted correctly, further enhancing their critical thinking and categorisation skills.
