# Max Maths, Year 2, Try it, Estimating numbers to 100

In a Year 2 maths lesson from Max Maths, children are learning to estimate and compare numbers up to 100 using a number line. In one activity, they are asked to place the numbers 67 and 76 on a number line that includes the numbers 60, 65, 70, 75, 80, and 85. The children learn that on a number line, numbers increase in value as you move from left to right. Therefore, since 76 is positioned to the right of 67, it is the larger number. To express this, they write 76 > 67, with the symbol '>' meaning 'greater than'.

The next task involves arranging three numbers - 80, 72, and 94 - in descending order. By placing these numbers on the number line, students can visually determine their size relative to one another. From right to left, they observe that 94 is the largest, followed by 80, and then 72 is the smallest. The children then arrange the numbers from the biggest to the smallest using the 'greater than' symbol, like this: 94 > 80 > 72. Through this activity, they reinforce their understanding of the symbols '<', which means 'less than', and '>', which means 'more than'.
