Length and height - Subtracting lengths - Starter

In the context of a Year 1 mathematics curriculum during the Spring Term, Week 9, Day 4 introduces young learners to the concept of adding lengths through practical examples. The children are presented with an exercise where they calculate the collective length of erasers, each measuring 2cm. They are asked to find the total length of 3 erasers, which is 6cm, and then 5 erasers, amounting to 10cm. This exercise encourages them to count in multiples of two and reinforces their addition skills. Additionally, the students are prompted to identify various shapes, such as circles, triangles, squares, cones, cylinders, and pyramids, and to determine which groups represent a set of five, further developing their recognition of geometric shapes and understanding of grouping and numbers.

Progressing to Week 9, Day 5, the focus shifts to combining subtraction and addition within the 'Fluent in Four' revision section. The children practice simple arithmetic by calculating that sixteen minus seven equals nine, and that nine plus eleven totals twenty. They are also engaged in an activity to match balls with corresponding numbers, enhancing their number recognition and matching skills. In a pattern continuation exercise, students are encouraged to identify sequences, fostering their analytical thinking. Finally, they compare the heights of different balloons, determining which is taller and by what margin, an activity that introduces basic measurement comparison and spatial awareness. The exercises are designed to be interactive and enjoyable, ensuring that children remain engaged while learning fundamental mathematical concepts.
