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

In this engaging lesson, students will learn the concept of counting to 100 by making groups of 10. The lesson starts with a discussion, prompting students to think about whether counting in 1s is the only method to reach a number and whether there's a faster way to count to 100. Using ten frames filled with counters, the lesson illustrates that one ten frame represents 10, two ten frames represent 20, and so on, building up to the concept of counting in tens. Students are encouraged to spot the pattern as they work with ten frames, each representing an increment of 10, and to predict what four tens or five tens would look like, with the aim of understanding that four tens equal 40 and five tens equal 50.

The lesson continues with the use of a number line to reinforce the concept of counting in tens both forwards and backwards. Students practise counting from 0 to 100 and back down to 0 in tens, with each step visually represented on the number line. The practical application of the lesson is further enhanced by grouping objects, such as hands and bears, into tens to simplify the counting process. For example, two hands together make 10, and students are guided to count groups of 10 bears in boxes, eventually adding on individual bears to reach the final count. The lesson concludes by encouraging students to practise grouping counters or other objects into tens and counting to determine the total, thus reinforcing their understanding of place value and efficient counting methods.
