Place Value within 20 - Count and write numbers to 20 - Worksheet

The "Place Value within 20" worksheet is a carefully structured resource aimed at helping Year 1 children grasp the concept of counting and writing numbers up to 20. The National Curriculum objective for this lesson is for children to count to and across 20, both forwards and backwards, starting from any given number, and to read and write numbers from 1 to 20 in both numerals and words. The worksheet offers differentiated sheets and teaching slides, as well as concrete equipment to support the learning process. Key vocabulary includes terms such as 'count', 'numbers', 'forwards', 'backwards', 'teen', 'after', and 'before', which are crucial for understanding the lesson's concepts.

Children will deepen their understanding of place value as they explore numbers 11-20, paying particular attention to the 'teen' suffix and its significance in denoting the number. They will practice writing numbers in both numerals and words, using a number track as a visual aid. This activity helps them to identify patterns in number sequencing and understand the relationship between spoken and written number forms. The worksheet challenges children to fill in missing numbers on a number track and to solve reasoning questions that require them to count forwards and backwards up to 20. Through these exercises, they will reinforce their fluency in number recognition and place value knowledge.
