# Emergency Maths Lessons

## Here are some mathematics lesson plans to be used on the rare occasions when a class is left without their normal teacher and you are stepping in at a moment's notice.

### Transum > Emergency Lessons > Polygons

• Starter: Mathterpiece - Memorise a picture made up of geometrical shapes
• Polygons This drag and drop activity will enable the pupils to revise the names of the common polygons for themselves. You may decide to ask pupils to do levels two and three too. These levels cover line and rotational symmetry of these polygons.
• Polybragging This is game pupils can play in pairs. Each player clicks the 'next shape' button (while the other player isn't looking) and the computer selects a shape at random. The players each choose a property that they would like to play with and click that button. The players can now look at each other's shapes and the scoring is worked out. Whoever has the largest value for player 1's property wins one point.
• Polygon People You may want to skip this activity if the pupils are deemed to be confident naming polygons. Otherwise this could be an opportunity to ensure everyone know how to spell difficult polygon names such as parallelogram!
• Polygon Pieces This is a great activity and is presented as a series of challenges in increasing order of difficulty. Pupils are asked to arrange the nine cards on the grid to make named polygons. The fun starts when a number of different shapes can be constructed by arranging the cards in different ways. The higher levels are only unlocked after the lower levels have been completed.
• Online Logo There is no better way to learn the way to calculate the exterior angles of a regular polygon than using this dynamic programming platform. The collection of 30 challenges take the pupil from the basics to some quite sophisticated computer programming.
• Polygon Angles Finally here is a more formal exercise on calculating the angles in regular and irregular polygons. The exercise has a number of levels and includes a number of exam-style questions,

The activities above will probably give you a series of lessons rather than just one.

• Finisher: Tardy - Tardy Tranter has finally turned up to the lesson ten minutes before the end. You have been assigned to teach him what he has missed. You have a couple of minutes to prepare any notes or diagrams you may need.

It doesn’t happen very often but sometimes you find yourself in the position of having to deliver a lesson at a moment’s notice. In the worst case scenario you do not know what the class have previously been learning and you have been given no information about the nature of the pupils from their normal teacher.

These lesson plans have a low threshold, high ceiling so can be great learning opportunities for a wide range of pupils and class dynamics. No preparation is required as all of the activity details can be found by clicking on the links in the plans.

If pupils complete the activities online and earn trophies as a record of their progress teachers (who are Transum subscribers) can see from their class list which pupils have earned which trophies.

Furthermore if pupils do have access to internet connected computers see Laptops In Lessons for more lesson plans. If they have iPads there are some ideas on the iPad Maths page.

There is a printable page called Lectio Tumultuarios (Latin for Emergency Lesson) designed for Maths tutors (who are Transum subscribers) to have printed and stored in their folder ready to use on the odd occasion when a quick five minute time filler is required.

"My extreme emergency lesson (back in the day) was the Four Fours challenge. It was sort of an HCF of all the classes I was likely to have to cover and required no equipment or preparation.

The objective of this challenge is to find the simplest mathematical expression for every integer from one to some maximum (depending on the class), using only common mathematical symbols and four copies of the digit four.

Nowerdays if you want to issue this challenge to a class you could do it using a different digit by using the 4th July Starter page as a projectable visual aid."
