Short, scaffolded worksheet for adding and subtracting fractions. For lower ability group. (25/1/19 PDF version added.)

A set of spreadsheets for use in ICT, with links to history, geography and PE. The intention is for learners to be able to sort, select and analyse data from a larger data set. The files are: - Monarchs (English/British from Alfred) with dates, ages, spouses and children - HDI data on countries in 2000 (the distinction for LEDC and MEDC was arbitrarily drawn) with population, GDP, literacy and other measures - World cities 2004 with population (over 1m), country and rank - 2012 athletes with country, height, weight, sport (but not medals) - World top track times 1999 with event, gender, country, name, time, rank, date - Periodic table with name, symbol, mass, density, melting, boiling

Add/subtract mixed with multiply/divide, seeking to clarify which signs you need to look at when deciding how to use signs in the answer. Straight-forward worksheet (2 copies per sheet - chop in half!). (12/7/16) Answers uploaded

A presentation showing how to divide by (say) 0.2 or 0.5. Introduces idea at the end of rewriting the sum by increasing both dividend and divisor by power of ten. Supporting file has decimal number lines (0-5, 3 different sets of scale markings) for printing on A3 for students to use - you may want to cut up and laminate. [15/7/15 improved from user feedback]

Partners take turns to coach each other in rounding numbers to required decimal places or significant figures.

Scaffolded worksheet for converting decimal with second or second/third digit from decimal recurring.

Presentation that introduces factorising by trying to split arguing kids into equal groups with equal numbers of adults. Goes on to algebraical representation without pictures. Worksheet and answers now together here

Simple complete the table and answer a few questions exercise. (12/7/16 Corrupted resource reinstated)

Structured worksheet for dividing by a simple decimal. Uses principle of finding a similar calculation that gives the same answer - so instead of 36 / 0.09, find 3600 / 9. (12/7/16) Answers uploaded

Quick activity with six pairs to match up.

Mainly various equations - various levels of difficulty, both 1 and 2-step (12/7/16) Further equations and answers uploaded

20 quick questions. Use scale on left to get middle value (eg. between 5 and 6) or to establish the increments on the scale. 2nd question, fill in two more values on scale on right based on that answer. Repeat x 10. (Most increments are 10, but some are just five 'per unit'. One, two and 3 decimal places.)

6 tables to complete as source data for drawing pie charts. All integer values.

Spreadsheet that calculates chronological ages. It works (I hope!) correctly for months of different lengths etc. (No awkward cludges of dividing days by 30 to get months.) First tab on the sheet is set up so you can enter a whole class. The second tab is just for quickly checking single dates of birth. The main calculations in the first tab are carried out in columns D to J, which are hidden. If you look at the formulae, you will see that the formula is far from elegant - but calculating chronological ages is not an elegant process! I realise that the year calculation could be simpler, but I couldn't be bothered to edit it...

Promethean flipcharts demonstrating surface area and volume of solids. Versions for ActivInspire (Flipchart) and ActivStudio 3.5 (Flp).

Quiz, loosely based on Deal or No Deal. #1 has brackets but easier numbers; #2 has (simple) algebraic fractions; #3 negative and decimal answers. The player has an amount of money. The boxes contain algebraic expressions that say what that box is worth. So, if the player has £100, 2x+50 gives a box value of £250. It could equally be played as a quiz between two teams or individual players trying to get the highest value box. Original idea inspired by CrazyTalk clips on YouTube linked by Keith Ennis.

Brackets are compared to party bags! So expanding is just finding out how many items altogether. Hopefully simple, visual explanation of concept followed by some quick questions. Used alongside mini-whiteboards.

Scaffolded worksheet on fractions of an amount using fairly simple quantities.

This links factorisation of linear expressions (where the term in the bracket is in the form y=m(x + c/m)) to the intercept with the x-axis. It lays the foundation for the same concept when factorising quadratics. It could be developed by examining y = c - mx or y=m(ax + c/m).

Promethean flipchart demonstrating percentage increase and decrease. Authored in ActivStudio 3.5 but should import into ActivInspire.
