Resource title: Averages and range spiders
Resource author: alutwyche
What is it?
I'm officially declaring 2017 as the year of the spider! Another great example of a spider-style activity, this particular resource tackles the topic of averages and range.
In pairs, students complete a list of five numbers, taking care to choose a digit that matches the conditions of each leg. By challenging pupils to think in reverse, these worksheets help to consolidate knowledge of a topic often dominated by abstract, easily forgotten rules.
How can it be used?
This works best when students are comfortable with the basics, so I'd suggest recapping the concepts of mean, median, mode and range before unleashing the spiders. During the activity, make sure that learners have plenty of time to discuss their answers, not least because there’s often more than one solution.
Once mastered, why not task them with creating their own versions? You can really test their understanding by adding in a constraint - that the same answer can't appear more than once.
