A number problem for year 1 children to solve involving triangular numbers. We had been looking at different methods the children could use to solve number problems, e.g. drawing diagrams, using apparatus, making playdough models, etc.. They worked in pairs or small groups to encourage them to talk about their approach. The problem is easily differentiated by changing the final number. More able children and those in higher year groups could look at the pattern and think about rules for solving the problem regardless of the number given.

These are one step more and less problems that I've been using in Year 1. We're practising the vocabulary of 'more' and 'less' and their association with add and subtract. I'm also doubling up on a bit of "know and recognise the value of different coins." The last three slides require secure understanding and reasoning skills and so are good for extension or mastery/more able work. They ask questions such as: "Stu has 8p. Every week he spends 2p on sweets. How many weeks will his money last for?" Or: 'Amandeep has 2p. Meera has 5p more in her purse. Which coins does Meera have in her purse? Can you draw all the different combinations of coins that Meera might have? I hope you find it useful!

A range of Carroll Diagrams for the classification and sorting of information. Themes include categories such as odd/even numbers, in the 5 times table/not in the 5 times table which hit multiple maths curriculum targets in one activity. Alternatively, there are cross-curricular and popular culture themes, e.g. animals, Star Wars and Pop Artists. National Curriculum: - interpret and construct simple tables (Year 2) - interpret and present data using tables (Year 3) - identify and describe the properties of 2D shapes, including the number of sides and line symmetry in a vertical line (Year 2) - identify right angles (Year 3) - recall and use multiplication and division facts for the 2, 5 and 10 multiplication tables, including recognising odd and even numbers (Year 2) - use the language of more than, less than (Year 1)

Eight pages containing 32 progressive, pirate themed, 2-step word problems involving addition and subtraction. Each word problem is printed on a mini-treasure map and is intended to be stuck in individually so that working out can be shown around the word problem. The learning journey in this document is as follows: - Addition/subtraction of single digit numbers; - Addition/subtraction of 2-digit and single digit numbers; - Addition/subtraction of 2-digit numbers and tens; - Addition/subtraction of 2-digit numbers. Mathematics programme of study - Year 2: Pupils should be taught to: - solve problems with addition and subtraction. - add and subtract numbers using concrete objects, pictorial representations, and mentally, including: - a two-digit number and ones - a two-digit number and tens - two two-digit numbers - adding three one-digit numbers

We've been teaching number bonds for a few weeks now. It makes me nervous to spend so long on a single objective but I am noticing fringe benefits. Obviously, the children are all doing well with their number bonds but they are also using and embedding their understanding of + and = symbols which they now all use without thinking. Also, somewhat subconsciously, they know what addition is. Many children are starting to notice the commutativity of addition and share what they've realised in plenaries. As they have noticed it for themselves, they really get it, which is great. I'll be using the same resources to teach related subtraction facts shortly and I'm hoping all the solid work we've done on number bonds to date will give us a good springboard for subtraction and its relationship to addition. This resource contains: - a range of number bond printables for 3 strategies - grid, bar and cherry picking. - a range of mastery printables to extend more able children and embed learning. - a few photos of the children's work. Year 1 national curriculum objective: Pupils should be taught to represent and use number bonds and related subtraction facts within 20.

Use these Christmas calculations to challenge your pupils’ understanding, ability to reason mathematically and algebraic thinking in a fun and engaging way! Using images to represent numbers, children use what they know to discover the value of the images. They need to understand the meaning of =, + and - signs and the relationship between addition and subtraction. The calculations include doubles and number bonds to 10 and 20. There are 4 sets of progressively more difficult calculations, as well as 4 sets with the numbers given in an answer key for children requiring more support. There are two open-ended calculations where children can find multiple possible answers to extend pupils’ thinking. Further extensions include children writing their own challenges or describing how they solved the problem. There is a multiplication and division version of this resource here. Happy teaching!

Happy Halloween! This product contains 20 Halloween-themed addition and subtraction word problem task cards within 20 and an answer key. These task cards are progressively differentiated as follows: addition and subtraction of single digit numbers within 10 with images for scaffolding single digit numbers within 20 1-digit and 2-digit numbers within 20 (without crossing the 10s boundary, e.g. 11 + 3 = 14) 1-digit and 2-digit numbers within 20 (crossing the 10s boundary, e.g. 14 - 6 = 8) open-ended questions to promote higher-order mathematical thinking (provide concrete resources for students requiring more support; encourage systematic working and challenge greater depth students to provide alternative solution pathways or explanations of all possible solutions). Task cards are provided in full colour and in black and white. Follow me on TES to be notified when new resources are added! Happy teaching! Katharine7

Looking for a fun and low-prep way to teach, reinforce or assess conceptual variation of number? This resource provides multiple representations of the numbers 1 - 10, supporting children to develop a deeper understanding of each number. These number representation matching activity mats are great as an independent activity for maths mastery, interventions, assessment or to create a collaborative display with the children. Activity mats from 1 - 10 are provided along with a variety of number representations including: ten frames numerals words subitising - dice irregular arrangements - sweet jars tallies The activity mats and representations are available in full color or black and white. You could use them as a cut and stick activity or laminate the mats and number representations for a reusable activity. You could use the activity mats by themselves as a coloring and drawing activity requiring a more secure understanding of number.

I put together these revision slides for my less able Year 4s. When it came to maths papers, they persistently forgot 'easy' maths that they could do in class, so we revised them to death with these slides for some easy points on the papers!

My class enjoyed Frooby so I did another one for them. This time focussing on halves, both numbers and shape.
