Multiplication and division - Recognise equal groups - Starter

In the Year 2 mathematics lesson, students are introduced to the concept of recognising equal groups through a series of engaging activities. The lesson begins with a 'Fluent in Four' revision exercise, which includes a variety of addition problems such as finding half of 30 and then adding 74, and a simple addition of three single-digit numbers. The exercises are designed to reinforce mental arithmetic skills and set the stage for the day's learning focus. Additionally, students are tasked with using a ruler, although not to scale in the exercise, to measure heights, further integrating practical maths skills into the lesson.

The main activity involves understanding arrays by filling in a table with the number of columns and rows and the corresponding number of balls in each. This visual approach helps students grasp the concept of multiplication as repeated addition. For example, they explore how six columns with three balls in each result in a total of 18 balls, reinforcing the relationship between arrays, columns, rows, and addition. To apply their learning in a real-world context, the children solve a problem involving teddies in a box, adding more to find the total number. This hands-on approach helps solidify the mathematical concepts of addition and multiplication in a way that is relatable and easy to understand for Year 2 students.
