Place value within 100 - Introducing the 100 square - Presentation - Starter

In a presentation focused on understanding place value within 100, Year 1 students are introduced to the concept of the 100 square. The lesson includes a variety of activities that encourage the pupils to strengthen their numerical fluency and revise their subtraction skills. For instance, they are asked to solve simple subtraction problems such as "12 minus 5" which equals 7, and to perform operations that combine doubling and halving, like "double 5 minus half of eight" resulting in 6. These exercises are designed to help the children become more confident in their mental arithmetic abilities.

Another key part of the lesson involves counting backwards and identifying missing numbers in a sequence. Students use number tracks as visual aids to fill in gaps within a descending series of numbers. For example, when presented with the sequence "57, 56, ____, ____, ____, 52, ____, ____, ____", they are expected to correctly fill in "55, 54, 53, 51, 50, 49" to complete the pattern. Additionally, the children learn to compare quantities using terms like 'equal to', 'greater than', and 'less than'. They apply these concepts to complete sentences and solve problems, such as determining the total number of socks represented in ten frames, which in this case is 24. These activities are designed to enhance the students' understanding of numerical order and comparison, which are fundamental skills in their mathematical development.
