In a Year 2 maths lesson from Max Maths, children are learning to estimate numbers up to 100 in a practical and engaging way. Padma demonstrates this by counting a row of 10 jelly beans and then multiplying the number of rows by 10 to reach an estimated total. This method of estimation teaches children to use addition in steps of 10, a skill that is foundational for understanding larger numbers and basic arithmetic. By adding 10 repeatedly, Padma arrives at an estimated total without the need to verify the exact count in each row, since the goal is to practice estimation rather than precise calculation.

The activity illustrates that estimation can be a useful tool for quickly gauging the quantity of items. Padma adds together six tens (10 + 10 + 10 + 10 + 10 + 10) and concludes that there are approximately 70 jelly beans. The actual count of jelly beans turns out to be 67, showing that her estimate was quite close to the real number. This example reinforces the concept that estimation is about making an educated guess that is near to the actual amount, rather than an exact figure. Such exercises are crucial in helping children develop number sense and the ability to make reasonable approximations, which are valuable skills in everyday life.
