**Starter:**Aunty Dotty - A real life situation requiring the division an amount of money according to a given ratio.

- Dividing in a ratio This is to consolidate the method of dividing in a given ratio as introduced in the Starter. It is a slide presentation in the form of a poem with some questions at the end which can be done as worked examples if necessary.
- Ratio Exercise Choose the appropriate level for your pupils. The exercise is self-marking and pupils can earn a trophy for completing a level. Here is some information about viewing the trophies pupils have earned.

Call the class together for a plenary recapping the core ratio concepts. The Random Name Generator could be used at this point.

- Pattern Clues For this part of the lesson it is recommended that pupils work in pairs (You could even use the random generator above to assign random pairs - there are many otions in the left side bar of that page). Pupils are challenged to recreate the predetermined patterns by using the clues provided.

**Finisher:**Shark's Dinner - This is the mathematical version of the old game called hangman. The teacher (or computer, see link below) thinks of a mathematical word and writes dashes on the board to represent each letter of the word. Pupils have to guess the letters each of the dashes represents. If eight incorrect letters are suggested the game ends and the teacher has won. This game can also be played as a two team game. One team continues selecting letters until they select one that isn't in the word. Then the other team starts their turn. The winner is the team that completes the word.

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."
