Lesson Stages	Learning Activities	Time Allotted
Warm-up	Assess understanding and connect to their previous knowledge of percentages by giving an easy “fraction to percentage question” Ex: 5/20 -> 25% Present this warm-up as review (because we did this last class) Present hard fraction as an intro to this lesson: 27/43 -> 62.79%	4-5 mins
Middle	Evan- multiply both top and bottom by a number to get the denominator as close to 100 as possible	3-4 mins
	Jessica- add or remove some amount from the numerator until the fraction is simple and can be simplified	3-4 mins
	Jacky- Use a calculator  *Con is when stuff is simple*	1-2 mins
Recap	Discuss pros and cons of strategies and which they prefer. In what situations will some estimates be better or worse? Encourage them to make up their own strategy All of class has to tackle 27/43 -> 62.79%	6-8 minute
