Addition and subtraction within 10 - Finding a part - Starter

In the initial stages of learning mathematics, Year 1 students are introduced to fundamental concepts of addition and subtraction within 10. On the first day of Week 8 in the Autumn Term, the lesson plan focuses on 'Finding a Part' using a practical and visual approach. Students are provided with 10 counters to aid their understanding of part-whole relationships. The 'Fluent in Four' revision activity is a key component of the lesson, helping to reinforce the children's fluency in basic arithmetic operations.

The main activity involves completing a part-whole model and using it to construct number sentences. For instance, when given the whole number 8 and one part as 2, students must determine the missing part and then write the corresponding addition sentences, such as '2 + 6 = 8' and '8 = 2 + 6'. Additionally, they are tasked with ordering numbers from least to greatest and predicting the next items in a given pattern. The counters play a crucial role, enabling the children to physically manipulate the numbers to better understand concepts such as doubling, where they calculate 'Double 2 + 2' to find the answer. This hands-on experience is vital in building a strong foundation for mathematical reasoning and problem-solving skills in young learners.
