In this March overview for Operation Maths users, there are links to topic-specific posts and articles, as well as a whole host of extra suggestions, links etc. To ensure you don’t miss out on any future Maths by Month blog-posts, please subscribe to the blog via email, on the top right hand of this page.

*Pssst! The Edco Primary Publications launches for 2018 will be taking place in March and April in Kilkenny, Dublin North and South, Limerick, Cork, Galway, Athlone and Wexford. As well as launching Number Facts 1-4 and Bua na Cainte 3, they will also be showcasing Operation Maths and Exploring Spelling. Click on the link above for more info and to register.*

### Operation Maths Jr Infs to 2nd classes:

**Junior Infants**will be exploring representing and interpreting Data (week 1), exploring aspects of Shape and Space via 2D shapes, 3D shapes and spatial awareness (week 2), and developing an understanding of the concept of Time via sequencing of familiar daily events and the days of the week (week 3). As usual, a whole suite of supporting activities are detailed in the TRB as well as ideas for Aistear play.**Senior Infants**will be exploring Length (week 1), as well as being formally being introduced to the number 10 (week 2) and then exploring 10 further by investigating the different combinations that make up the number 10, using a variety of models including the Operation Maths ten frames (week 3). They will also further consolidate their understanding of patterns (Algebra) and graphs (Data) via linked activities. As mentioned previously, the Number Talks resources for the number 10 available at the link are very applicable as well as the practical activities and stations using concrete materials, that are suggested in the TRB.**First Classes**will be looking at Length, Operations and Fractions.

In Operations, the children will be exploring addition and subtraction without renaming. On many of the pages in the * At School* books the calculations are presented horizontally. This is deliberately done to encourage the children to complete the calculations using concrete materials, pictorial representations and/or mental strategies, as opposed to always using the vertical column method. While the development of traditional written procedures (eg the column method) is still important, these written methods

**are not more important**Some of the mental strategies for addition and subtraction, used in Number Talks, would also be every useful here e.g. partitioning, friendly numbers, making tens (compensation) and removal (deduction). Suitable number strings can be accessed at the link above and of course teachers can make their own number strings based on the horizontal calculations in their At School book, for example, from page 93 (four calculations in each number string works well) : 39 – 7, 39 – 0, 39 – 1, 39 – 9

**Second Classes**will be spend most of this month (week 1 & 2) working on operations; addition, without and with renaming, and subtraction without and with renaming, the latter of which is new content while the other material will be revision of first class work. Concurrently, they will will also be revising place value to 99 as the basis for the work on the operations.On many of the pages in thebooks the calculations are presented horizontally.

For second class, week three will be concerned with Length and the formal introduction of the centimeter as a standard unit of measure.
