# Max Maths, Year 3, Learn together, Counting up to 1000 (4)

In this engaging activity from a Year 3 mathematics lesson, students explore the concept of counting and building numbers using counting blocks. Tya, a character in the lesson, begins by creating the number 900 with these blocks. To visualise this, students are prompted to consider that Tya has used nine hundred blocks to represent the number, as each block signifies a hundred units. The blocks are laid out as a tangible representation of the number, making it easier for young learners to comprehend large numbers.

The activity progresses when Jade, another character, contributes to Tya's creation by adding one more hundred block to the existing collection. This simple action provides a practical example of addition in hundreds, taking the total count from nine hundred blocks to ten hundred blocks. Students then learn that this new total of blocks represents the number 1,000, which is verbally expressed as 'one thousand'. This hands-on approach helps to solidify the students' understanding of counting in hundreds and the concept of reaching a thousand through accumulation.
