As 2019 draws to a close it seems appropriate to mention Jane Hart’s annual Top Tools for Learning 2019, an annual list I have always been interested to see.
With the majority of respondents coming from the workplace and just 22% from education, perhaps a list of particular interest to readers of this blog is the Top Tools for Higher Education (EDU100). I was interested to see that Padlet, an excellent online noticeboard which has been around for a long time remains popular, and verified for me by a favourite source, Richard Byrne’s Free Technology for Teachers in his ‘My Favorite New & Updated Tools in 2019‘ post.
Excel is quite rightly, in my opinion highly placed. I regularly use Excel resources; just a few examples of some favourites:
I first came across and enjoyed a Futoshiki puzzle in the Guardian puzzles section.
Work out the digit that goes in each cell. In this 4×4 example, the digits from 1 to 4 must appear exactly once in each row and column.
Initially, some digits might be revealed and additionally, the board might also contain some inequalities between the board cells; these inequalities must be respected and following them will help you find the missing digits.
In the above puzzle, difficulty level, easy, we see that the fourth column already has a 1 and a 3, the remaining digits 2 and 4 can only be placed one way as we have to follow the inequality sign.
On Futoshiki.org from Vlad Daskalu, you can generate puzzles of sizes from 4×4 to 9×9 and choose one of 4 difficulty levels.
Other sites offering these puzzles include Brain Bashers where you can play a wide variety of puzzles, see the choice from the home page.
There is, of course, an app for that, you’ll find Futoshiki available for Android and iOS. The holidays offer a chance to explore some more puzzle apps and games. I have some details of various apps on this page. Have you tried PhotoMath? Some of my Sixth Form students were checking some integration examples using this recently, it seems very easy to use and for the examples I tried looked very helpful.
For many more online puzzles to amuse you over the holidays try the Puzzle collections on Mathematics-Games.
Yohakuis a puzzle that will test your number sense and problem-solving skills. Each Yohaku puzzle is either an additive or a multiplicative puzzle. You must fill in the empty cells such that they give the sum or product shown in each row and column as well as satisfying a rule if given.
Non-Examples – Expressions and formulae, Andy Lutwyche
From Andy Lutwyche try Non-Examples – Expressions and Formulae – Reasoning Tasks, a resource with seven sets of five questions and solutions, some of which are correct and some of which are not. Students decide which are correct and explain how they have come to their decision. The topics covered are simplifying expressions, substitution, expanding and factorising expressions including quadratics, rearranging formulae and algebraic fractions. Resources like this can promote excellent class discussion.
I used a favourite Underground Maths resource this week – To log or not to log? This has worked really well every time I have used it. The activity requires students to think about the methods which could be used to solve the various equations. I have always found that in addition to working on indices and logarithms this task has exposed some misconceptions, with students trying to invent some new and invalid laws of logarithms!
Students are often used to problems being posed in such a way that they have all the information that they require in order to start, and no more. Problems (especially from the real world) are very often not like this, and so resources of this type will give students the opportunity to develop the skills needed to deal with this. Some problems might not contain enough information, so students may need to decide on classifications, make assumptions or approximations, or do some research in order to move forward. Some problems might contain too much data, so that part of the challenge is to identify the useful information.
When students are familiar with concepts and ideas they often benefit from exploring them further to improve their understanding. These problems aim to allow this further exploration, and for example, might bring different techniques together, highlight interesting or unusual cases, or probe the definition of mathematical terms.
Year 13 will get that card this week, thank you Matthew!
Teachit Maths – Advent Calendar
On the subject of Christmas, there are still loads of doors to open on those Advent Calendars and if you are looking for activities for the last week of term, try the Christmas 2019 collection.
AQA – Maths Digest From AQA, have a look at their Maths Digestwritten to support Mathematics Teaching and learning. Useful whichever examination board you use, the digest offers tips and resources. I do like “Small things make a big difference” on avoiding common exam mistakes. This PowerPoint highlights where marks are often unnecessarily lost.
“Top tips for perfecting exam techniques” by Julia Smith provides her top tips to help students perfect their exam technique and to help gain crucial marks. In the article, Julia refers to AQA’s list of command words, so useful to show your students.
See also Reference for further resources on mathematical vocabulary.
This can be used in class by asking students to plot the points, draw their lines of best fit and then comparing with the computer. This worked really well on my phone, I simply sent myself an email with the link and was able to move points easily. This could also be used with younger classes when talking about lines of best fit.
Choose from a range of examples or choose Custom to add your own points and guess then check the correlation coefficient. You can also draw your own line of best fit and compare it to the theoretical line of best fit. Note the option to include residuals for both your own attempt and the line of best fit.
For more on resources for Regression see this post; you could also use Desmos, GeoGebra, Excel or WolframAlpha.
Remember we have the wonderful collection of Advent Calendars to use in the run up to Christmas. I was amused at a comment from Plus Magazine regarding the inclusion of cute kittens wherever possible! Behind Door 1 of their 2019 advent calendar you will find the story of a rather important cat: Schrödinger’s cat!
From the ATM for younger children, Midwinter Mathematics is a downloadable collection of mathematical activities, problem-solving and investigations that are suitable for the winter term for Primary Classrooms. Check ‘Look Inside’ for two free activities, Christmas Stockings where children can think about systematic listing strategies by working out the number of arrangements of Christmas Stockings and Paper Chains, a practical task where children use a piece of A4 paper to make the longest paper chain they can.
On the subject of paper chains, with a twist on the relay idea this TES resource, Chrismas Paper Chains, has students racing to make the longest Christmas paper chain.
Available from STEM Learning, Winter Mathematics from the Shropshire Centre for Mathematics education consists of twenty eight winter-themed activities for younger students (ages 5-11). The collection consists of a variety of investigations, puzzles and games covering many aspects of mathematics.
Also available on STEM Learning, see Christmas Puzzles; The National Centre for Excellence in the Teaching of Mathematics (NCETM) published four seasonal puzzles from Amusements in Mathematics by Henry Ernest Dudeney, published in 1917, in their Secondary magazine. I have mentioned Henry Ernest Dudeney’s – Amusements in Mathematicsbefore (see Free Books), the Kindle edition is free. Several categories of puzzles are available. A search on Christmas returned 23 puzzles, solutions are all provided.
I often mention the Perton Maths Department, check #PertonChristmaths for their seasonal Challenge collection.
Sign up to the IMA e16plus Newsletter which is aimed at 16 – 19 year olds who are interested in mathematics and check the latest edition which includes two competitions to enter over the Christmas break as well as various Christmas puzzles and articles.
From Teachitmaths, create a masterpiece! Mistletoe & lines; the description reads ‘Practise your graph drawing skills with a Christmassy theme! Plot the given points to draw a Christmas tree, then add your own lines of tinsel, giving the equation of each one.’ The pdf resource is free, you just need to register with the site. Further Christmas activities are available.
For more plotting, try this ATM open resource, Santa Plotting. Plot the points given and note the challenge questions at the end.
On TES we have a complete set of relays from Chris Smith; my classes have enjoyed his Valentine and Summer relays, I think we’ll use the Christmas relay to complete this term! You can find more excellent resources from Chris on TES and follow him on Twitter here.
As with all these relays from Chris – all the answers are provided – brilliant!
Another set of Higher (Geometry) problems is here. I like their festive Venn Diagrams, they would make a nice introduction / reminder on Venn diagrams for younger students.
From MEI, the November / December 2017 M4 Magazine includes an excellent collection of 10 puzzles and challenges for your students. Full teacher notes and solutions are included and the problems are ready for you to project for your classes.
Dr Matthew Lettington of Cardiff University has helped Admiral create an online tool to calculate how many baubles and fairy lights are needed for the perfect Christmas tree. Answer four questions to find out how many baubles and the length of fairy lights you need!
We could do the annual calculation and work out how many gifts are received over the 12 days of Christmas. Murray Bourne has all the answers and more on squareCircleZ or have a look at this YouTube video.
On the subject of videos, try a video advent calendar from Numberphile!
