In addition, an answer and detailed mapping sheet is now available to contributors.

Practise using reordering strategies with these extra E1 (E2 questions are in a separate Wordwall activity) questions for our recently updated E1-E2 Mental addition strategies (reordering) PDF worksheet (Maggie Harnew, 2005, updated Feb 2022). Match the correct answer to each addition problem. (Reordering involves adding up large numbers first and/or looking for pairs of numbers that add up to ten. **Can be used independently of the original resource.**

I've just designed these ready for my new starts in September. It is surprising how many learners come that get the simplest things wrong.

Specifically written to focus on the reformed Entry Level 1 ‘Number’ content, these worksheets follow Sam and Dot at their workplaces during the Halloween period. The resource draws on the different question styles used by the major awarding organisations and can be used for diagnostic assessment and revision.

Entry Level 1-2 Maths questions based on a shopping poster from the BBC 2018 Children in Need appeal but can be used at any time. Main focus is positional vocabulary, money and basic number (+, -. x, /) skills

**Editor's note**

Fully mapped to the new 2018 Functional Maths content which takes effect from September 2019 (note that times tables to 12 x 12 and basic division skills are now expected at E2). Image below shows , as an example, the detailed E2 mapping.

This is a MS Excel resource that is designed to be a useful resource for producing sheets for starter activities or homework. This also provides a tutor marking sheet. The sheet can be used to differentiate by choosing larger or smaller numbers, and can be addition or subtraction.

**Editor’s note**

Creates printable sheets of 20 problems (plus answer sheets). Clever and useful!

A practical investigation that can be enjoyed in mixed level classes. There's something for all learners from Entry Level 1 to Level 2.

**Editor's note.** One of my favourite resources that somehow got lost when the site was redeveloped in 2011. Now fully updated to reflect the new 2018 Functional Skills content that come into effect September 2019. Pages 7-8 show detailed FS mapping to content descriptors and problem solving skills.
