Place value - Counting in 10s - Worksheet

Introducing the concept of counting in tens, this worksheet is designed for young learners who have previously mastered counting in twos and fives. The activity uses visual aids such as pictures, bead strings, and number lines to facilitate the understanding of this new counting method. A hundred square is also provided to help children recognise the pattern that emerges when counting in tens. For beginners, a number line marked in tens is included to assist them in the counting process, while more advanced learners are challenged with larger numbers and fewer visual cues, encouraging them to count beyond one hundred and draw the amounts themselves.

The worksheet includes a variety of exercises to develop fluency and precision in counting. Children are prompted to calculate the total number of penguins on ice blocks or wolves on boulders by multiplying the number of animals by the number of groups, each consisting of ten. The exercises progressively increase in difficulty, with two-step problems that ask students to adjust their calculations based on hypothetical changes, such as adding or removing groups of ten. To deepen their understanding, children also engage in reasoning and problem-solving activities where they must determine the correctness of statements involving the grouping of items in tens and justify their answers, thereby reinforcing their numerical and analytical skills.
