Place value within 100 - Counting to 100 by making 10s - Starter

In the context of a Year 1 mathematics lesson, children are introduced to the concept of place value within 100, with a focus on counting to 100 by making tens. The lesson begins with a 'Fluent in Four' revision exercise, where students are asked to solve simple arithmetic problems such as doubling 5 and finding half of 0, leading to the correct answer of 10. Additionally, children practice adding numbers like 11 and 8 to reinforce their understanding of basic addition.

The lesson continues with activities designed to consolidate the learners' grasp of place value. They are prompted to complete sentences that help them identify the position of numbers in terms of tens and ones, such as "The ___ is to the left/right of the ___." This exercise aids in visualising the numerical order and understanding the value of digits within a number. Furthermore, using practical examples, students measure volume with small glasses as units, enhancing their comprehension of measurement and quantity. They are tasked with determining the volume of liquid in a bottle, expressed in the number of units, and showing a specific number using tens and ones, such as 16 being composed of 1 ten and 6 ones.
