Place Value within 20 - Tens and ones part whole model - Worksheet

The worksheet titled "Tens and Ones - Part Whole Models" is centred around the concept of place value within the numbers 1 to 20, particularly focusing on the understanding of tens and ones. This educational resource is aimed at helping children identify and represent numbers using both objects and pictorial representations, such as number lines. The worksheet encourages children to read and write numbers in both numerals and words, reinforcing their comprehension of the numerical system. The key vocabulary for the lesson includes terms like 'tens', 'ones', 'equal', 'represents', 'count', 'greater', 'less', and 'part-whole model'. Differentiated sheets, teaching slides, and concrete equipment such as Base 10 are provided to support various learning needs.

Throughout the exercises, children learn that numbers from 11 to 19 are composed of '1 ten and some more', while 10 and 20 are seen as whole tens without ones. The concept is further explored by comparing one ten to ten ones, and visually representing these with lines (for tens) and dots (for ones). Key questions prompt learners to think about the size of numbers, the 'teen' suffix, and the interchangeability of tens and ones without altering the total count. The worksheet activities range from writing the number of tens and ones for given numbers to completing part-whole models with visual aids. Children are also tasked with solving reasoning questions using the part-whole models and numbers up to 20, allowing them to apply their knowledge in problem-solving scenarios.
