Place Value within 20 - Tens and ones part whole model - Starter

In an engaging starter activity for Year 1 students during the Autumn Term, the focus is on reinforcing their understanding of place value within 20, using tens and ones in a part-whole model. The children are provided with 10 counters to help them visualise and solve simple subtraction and addition problems. They are tasked with exercises such as calculating the result of '7 minus six' and 'double 5 minus 6', using their counters to assist in finding the answers. This hands-on approach helps to cement their understanding of basic arithmetic by physically manipulating objects to represent numbers.

Additionally, the children are encouraged to use ten frames to visually represent numbers, further enhancing their grasp of the concept of place value. For example, they are asked to show the number 11 using the ten frames, breaking it down into tens and ones. This exercise not only aids in number recognition but also in understanding the composition of numbers within 20. To add a comparative element to the lesson, students compare quantities to determine who has more, such as between two characters named Zach and Leanna. This comparison task not only reinforces counting skills but also introduces the concept of comparison and quantity assessment in a fun and interactive way.
