Place value - Count forwards and backwards within 20 - Worksheet

The provided material outlines a series of worksheets and activities geared towards helping Year 1 children understand and practice counting forwards and backwards within the range of 20. The National Curriculum objective for this lesson is to ensure that children can count to and from 20, starting at any given number, and are also able to read and write these numbers in both numerals and words. The resources needed for the lesson include differentiated sheets for various levels of proficiency, teaching slides for visual aid, and concrete equipment to facilitate hands-on learning. Key vocabulary terms such as 'count', 'numbers', 'forwards', 'backwards', 'teen', 'after', and 'before' are emphasized to enhance the children's mathematical language.

Activities are structured to build upon children's existing counting skills, particularly focusing on the numbers 11-20, and to deepen their understanding of place value. The concept of the 'teen' suffix is explored to help children grasp its significance in denoting numbers between 13 and 19. The lesson addresses common difficulties children might encounter, such as distinguishing the individual digits within the words for numbers like eleven, twelve, and fifteen. Through a combination of counting exercises, writing numbers in words and numerals, and using number tracks, children develop fluency and precision in their counting abilities. The lesson also incorporates reasoning and problem-solving tasks, which challenge the children to apply their counting skills in various contexts and to identify patterns and oddities in sequences of numbers.
