One tree diagram, numerous questions to figure out a cheesy joke. This involves counters and replacement.

This is an activity designed to et students thinking about ratio but changing one value in a ratio to get another ratio. There are four ratios on each slide which get steadily more challenging and should create discussion. This also brings multiples and factors into play as well as simplifying/equivalent ratio.

More fish jokes to be discovered having done some maths; there are two to do here, the first dealing with integers that satisfy inequalities (including number lines) and the second that deals with solving inequalities. I use these at various different times of a lesson but clearly the choice is yours whether you use them or not and when! They are always popular even though the groans over the jokes get louder each time.

I realised that I didn’t have anything on currency conversion so I amended the situation and you get to reveal another lame fish joke. Typo corrected.

The usual thing: do some maths and find the punchline to a cheesy joke. Ideal for online learning or any other type of activity.

Four sheets where there are 6 questions but 10 potential answers; students are reassured by the answers being on the sheet allow the teacher to get on with helping those who require it. The sheets get increasingly difficult; I tend to use these as starters or as an initial task straight after the explanation.

There are 10 statements for students to decide whather they are true or false regarding a pair of box plots. This should encourage mathematical discussion and these sheets seem to work well online too.

Two more rounding-based tasks; answers are on the sheet but more than the number to questions to make guessing less easy but also allow those who have the confidence to continue without the need to ask the teacher to check, allowing the teacher to help those who actually require it. The truncation sheet also contains error intervals.

Erica’s homework is causing her issues, this time on representations of data. This one involves box plots, histograms and cumulative frequency graphs as well as talking about quartiles. Your class’ task is to explain where Erica has gone wrong and to correct her solutions.

This does exactly what it says on the tin… needed for a session with Year 6.

Casey is now on the final chapter of the AQA Further Maths Level 2 Certificate: matrices, including multiplying and transformations. Casey requires help because mistakes are being made; can your classes help and explain what Casey has done wrong? These work well as discussion activities in class in my experience, but use them (or not) how you wish,

This is a true or false activity designed to create discussion about stem-and-leaf diagrams. including using them to find the mode, median and IQR. These work well online but also in the classroom.

I needed something for this topic and this is what popped out. Whilst it is a true or false activity I would expect some good discussions to arise whilst doing this, with conversations along the lines of “how could we make this statement true?” either by changing the wording or the initial algebraic expression. I have found these activities really quite successful in online lessons as well as “normal” lessons.

Three sheets: one on rounding to 1,10,100, one on rounding to decimal places and one on rounding to significant figures. Answers are on the sheet but there are more answers than questions meaning that guessing less of an option and students can get on in the knowledge that their answer should be on the sheet somewhere. These have been useful in online lessons as well as “normal” lessons.

Three sets (based around number properties), ten statements and students need to work out if those statements are true or false. This involves union, intersection, subsets and probability involving sets. I have found that these encourage discussion in class.

This is an activity based on the daytime quiz show “Impossible” where a question is asked and three options given: one correct, one incorrect but could be correct if the question was slightly different (partial answer), and one that is impossible (cannot be the answer). This is designed to be a discussion/reasoning activity where students find the correct answer then discuss why the other two options are impossible or incomplete. Topics include HCF, fractions, percentages, bounds, standard form, ratio, proportion, indices.

This is aimed at AQA Further Maths Level 2 students but could be used in early A level lessons as something a bit different. Answer the questions, reveal the joke.

This worksheet deals with symmetry of quadratics, where a quadratic function intersects with the y-axis and turning points/vertices of quadratics. It is aimed at Further Maths Level 2 students but could be used at the top level of GCSE as well.

Having been over a load of exam papers recently I decided to put together some statements regarding number (odd, even, primes), use of the identity sign, graphs, ratio; there are seven slides in total (plus answers) with increasingly difficult statements to cater for a whole class. The idea is to generate discussion and mathematical thinking, probably at the start of a lesson but use it when you like (if at all).

This does what it says on the tin, nothing fancy. Reveal the joke, which is so bad it’s good…
