Place value within 100 - Partitioning numbers - Worksheet

The provided worksheet is designed to help children understand the concept of partitioning numbers within 100, with an emphasis on grouping in tens to determine the quantity of tens and ones in a given number. The children are not expected to master flexible partitioning at this stage, but they may naturally discover alternative ways to partition numbers. Using concrete resources, the children group objects into tens and ones, employing part whole models with pictorial representations to aid in visualizing the concept. They count the groups of tens and ones to figure out the total number represented, completing the part whole models and corresponding sentences to demonstrate their understanding.

Further activities on the worksheet encourage the children to explore partitioning numbers in various ways, including reasoning with numbers to determine the amount of equipment needed to separate a number into tens and ones. The tasks also include fluency exercises where children complete part whole models and sentences, such as "64 has ____ tens and ____ ones." To deepen their comprehension, the worksheet presents problem-solving scenarios where children determine how many pieces of equipment have fallen off a table when partitioning numbers like 56, 81, and 94. Additionally, the worksheet challenges children with reasoning questions where they must identify the largest number based on given tens and ones, and calculate how many possible numbers can be formed with three tens and fewer than five ones.
