# 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.

• Starter: Fractangle - Can you see what fractions of the shapes have been shaded? It is not as difficult as it first appears.
• Fraction Dissect  Pupils will need to be online for this activity. They are challenged to draw lines to dissect the rectangles to make the given fractions. This activity serves to remind pupils about the properties of fractions and to use their knowledge of equivalent fractions.
• Equivalent Fraction Pairs The Matching Game is probably the easiest of the Fraction Pairs games to begin with though there are other activities involving the same cards.
• Fractions This is the main activity for this lesson. A series of self-marking exercises on adding, subtracting, multiplying and dividing fractions. It is suggested that working is set out neatly in exercise books then the answers entered into the online form.
• Fraction Line Arrange the fractions in order from smallest to largest. There are three different fraction sorting activities which are best done online.
• Vinculum A challenge to find fractions which are larger than the previous fraction but less than one.
• Finisher: Hi-Low Predictions - The teacher has a set of large cards with the numbers 1 to 9 printed on (A large pack of playing cards would also work - Just one suit is needed). The cards are lined up, backs facing the class, on the pen rack of the whiteboard. All pupils stand up. The teacher reveals the value of the first card and the pupils guess whether the next card will have a higher or lower value (right hand up for higher and left hand up for lower). The second card is now turned around and pupils who got the wrong answer sit down. This continues along the line of cards. The last pupils to remain standing are the winners. If time allows discuss the probability of the situation.
Hi-Low Predictions

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."
