Prior knowledge:
All the students are expected to know:
What is mean, median and mode
Find mean, median and mode by using data.

( without Jokers, Kings, Queens and Jacks) •There will be three rounds. In each round students will get 7 cards. (Appendix 1) •Round one is mode. Whatever value cards are your mode, you get those points. If you get no mode, you get no points. If you have two modes, add the numbers together, to a max score of 10. So if I got dealt to 6s and two 8s I would have 6 and 8 as my mode. I add them together, but because the total is higherthan10 ,I just score 10 •Students will get 3 min time to do this activity

While doing the example tell students that total number of tally is the frequency. Give students the instruction that now we are going to do an activity that is an individual task. Distribute the sheet to individual students ( Appendix 2)

Tell them that to image that they all are in front of Ameenee building and they have to fill the tally marks on the colour of cars that passed by for 1 minute. There will be two times they have to practice to put the tally marks. Each time they will get 1 minute. From the tally they have to fill the frequency table and they need to find the mode according to the colour. Tell them to practice the tally marks according to the cars passing on the road which will be shown on the presentation. And they have to count the tally and prepare frequency table as well.
