Matho game or the percent word problems can be used as task cards when printed as multiple pages per sheet.
These percent word problems review all types of percent problems for 6th grade. I've used it to review with my 7th graders and PreAlgebra students also. Questions have students finding percents of numbers, finding the whole when given the percent and part, finding discounts/taxes/tips.
I like playing Matho (Bingo) in two different ways in my classroom.
Way one: as a whole class, played like traditional Bingo.
Way two: Have students in pairs. Give each pair the same Bingo board. Print the Powerpoint off by putting 6 or 9 slides on each page and have students (or you can prep ahead of time) cut out the slides as mini cards. Then students put the cards face down and draw a card, find the answer on the board and mark it, and then continue play. I have partners either compete against each other or work together to try and get a Matho. This way students can work at their own pace and once they get a Matho, they can keep playing and try to get as many Mathos as they can. They have to be ready to show me which cards gave them the four in a row to give them a Matho and show me their work
