Addition and subtraction within 20 - Assessment

The Addition and Subtraction within 20 Assessment for Year 1 students is a comprehensive evaluation of their arithmetic skills, focusing on basic operations with numbers up to 20. In this assessment, children are tasked with completing number sentences to demonstrate their understanding of addition and subtraction. For instance, they must find the missing number in the equation 7 + _______ = 17, which requires them to identify the number that, when added to 7, equals 17. This exercise helps to gauge their ability to perform simple additions that result in sums within the 20 range.

Another aspect of the assessment involves practical application, where students calculate real-world scenarios such as Tia spending 20p in a sweet shop. They must select the correct combination of sweets that add up to the total amount spent. Additionally, the assessment includes matching exercises where students join number sentences with the same totals and complete part-whole models, further reinforcing their understanding of the relationship between numbers. To assess their confidence level, students are invited to circle how confident they feel about their addition and subtraction skills. The assessment also includes comparison tasks where children use the symbols <, >, or = to complete number sentences, and word problems that require them to calculate changes in quantities, such as the number of dogs in a park or counters in a collection, after an addition or subtraction has taken place.
