Key Language and Representations Word Problems are the arithmetic number sentences written in a real-life reasoning and problem solving scenario. e.g. 3 + 4 = 7 Number Lines are used to count forwards e.g. 0, 1, 2, 3, 4, 5 and also to count backwards e.g. 10, 9, 8, 7, 6, 5.

Concrete Objects are manipulated or handled to calculate and represent a number sentence i.e. multilink cubes used for counting, sharing and halving. e.g. 3 + 3 = 6

Column Addition is the formal written method of adding two or more numbers together, using a vertical arrangement in a columnar format. 1s 3 + 5 8
10s 1 + 1 2
1s 0 0 0
1s 2 1 + 3 6
Column Subtraction is the formal written method of subtracting a smaller number from a bigger number, using a vertical arrangement in a columnar format. 1s 3 - 1 2
10s 2 - 1 1
1s 0 0 0
10s 1s 1 2 10 - 1 1 0 9 Regroup 1 ten into 10 ones.
Strategy Applied refers to when a formal written method is used to calculate a number sentence e.g. 25 - 5 = 20 Explained using appropriate mathematical language, proven using concrete objects that can be handled, shown with pictorial representations visualising the calculations, to ensure a greater understanding of a mathematical concept. Part Whole Models are pictorial mathematical images to represent varied calculations and number sentences. e.g. 6 + 3 = ? 9 6
e.g. 9

2 = ?7

?9

?7

Bar Models are an image, that pictorially represents a number sentence. e.g. 3 + 9 = ? 12 3
e.g. 20 -

Groups of objects represents a total number of objects shared or divided into two or more groups of an equal number of the objects. 1 of 10 = 5 2 Group 1 ● ● ● ●
