Place value - Tens and ones using addition - Planning

The Year 2 Autumn Place Value curriculum for Week 3 delves into understanding tens and ones through addition. The National Curriculum objectives set for this week include reading and writing numbers up to at least 100 in numerals and words, recognising the place value of each digit in a two-digit number, and using place value knowledge to solve problems. Children are also expected to compare and order numbers up to 100, using inequality symbols. Key vocabulary for the unit encompasses terms such as place value, digit, numeral, Base 10, and various other terms related to number representation and comparison. The lesson aims to build on children's prior knowledge and enhance their understanding of numbers using practical resources like part whole models and Base 10 blocks, alongside worksheets and presentations.

The specific lesson on 'Tens and Ones using Addition' encourages children to use part-whole models to partition and recombine two-digit numbers, reinforcing the concept that numbers can be expressed as the sum of tens and ones. For instance, the number 73 can be partitioned into 70 (tens) and 3 (ones) and then recombined to form the total. Activities include building numbers using Base 10, recording calculations, and discussing the commutative property of addition. The lesson also revisits the concept that the equals sign signifies 'the same as'. To stretch and challenge the children, they are reminded of the eight fact families and the relationship between addition and subtraction, with an emphasis on writing calculations to show the inverse operations. The session concludes with a reflective 'Give me five' activity where children consider what they've learned, the skills they've used, and what they found tricky, ensuring they remember the key points from the lesson. Differentiated tasks cater to varying levels of understanding, from working towards the expected level to achieving greater depth.
