Max Maths, Year 1, Learn together, Comparing numbers to 20

In a Year 1 maths lesson from Max Maths, children are encouraged to compare numbers up to 20 by counting seashells in different sets. The activity starts with three sets of seashells labelled Set A, Set B, and Set C, each containing a different number of seashells. Set A has 12 seashells, Set B has 16, and Set C has 15. The children are guided to count the seashells in each set and then compare the quantities to determine which set has the most and which has the least number of seashells.

Through this hands-on activity, the children learn that Set B, with 16 seashells, has the biggest number, while Set A, with 12 seashells, has the smallest number. The lesson then transitions to teaching the children how to arrange numbers in order. They practice arranging the numbers from the biggest to the smallest (16, 15, 12) and also from the smallest to the biggest (12, 15, 16). This exercise helps to reinforce the concept of numerical order and comparison. Additionally, the children learn about the concept of 'between' as they identify that the number 15 is between the numbers 12 and 16.
