This is a lesson to introduce the basic concept of the bar model. It covers addition and subtraction questions and includes both the powerpoint explaining what the bar model is and how to use it along with Higher (4 digit numbers), Middle (3 digit numbers) and Lower (2 digit numbers) ability questions and the matching answers for each.

This is a fantastic complete lesson pack which allows children to actively engage in Maths. **Included in the pack: ** White board resource Teachers instructions & answers Posters to put around the room Three differentiated question sheets. The children move around the room (or outside space) to answer differentiated (higher, middle and lower) maths questions. Once they have found the answer, they will jot down the accompanying letter. Theses letters, when unscrambled, will make a Christmas themed phrase. **Subjects covered: ** Halving and doubling. Number Sequences. Mental addition and subtraction. Rounding. Multiplication and division. Fractions. Decimals. Activity Instructions Place the posters around the room (or playground) and give children a question sheet each (or in pairs/groups). The children will answer the differentiated questions. Once they have found the answer, they will look around the room for the poster displaying that number and note down the corresponding letter. (Note: Remind children that some letters may appear twice.) Children must answer all of the questions and collect a total of 13 letters (some letters are red herrings!). These letters must then be unscrambled to find a hidden Christmas message.

Here we have 6 addition word problems. I have split each one so they can be cut and stuck into books easily. These are 2 digit add 1 digit, however could be quickly adapted to suit any numbers. There is also a challenge question at the end to extend those children who finished early.
