Teach your students how to subtract mixed numbers with like denominators by using this interactive/cut and paste activity!
This interactive lesson prompts students to create a 'Road Map' in which they decide which 'route' to take on their journey of subtracting mixed numbers. If the first numerator is greater than the second numerator, you can take the easy route of simply subtracting both the whole number and the mixed number. However, when the first numerator is less than the second numerator, you must take the other route by converting the mixed numbers into improper fractions and then subtracting!
This interactive lesson provides students with a hands-on activity to review Order of Operations using the mnemonic phrase ‘Please Excuse My Dear Aunt Sally’ to represent the order of parenthesis, exponents, multiplication, division, addition and subtraction.
This lesson will be sure to intrigue your students as it offers another approach rather than the traditional worksheet. I have found great success in incorporating interactive lessons into my classrooms and my students have thoroughly enjoyed each lesson.
I have provided a template in which the students will color, cut and paste to a separate sheet of paper *or could be a great piece to add to a math journal!
This product includes:
- A procedures page, including the Common Core Standard, step-by-step directions, a photo example and a proficiency scale for students to reflect upon the lesson.
- A 'Subtracting Mixed Numbers’ template
*This lesson is a part of an Interactive Math Journal that I use in my classroom but can be used as a single lesson as well. Check out my store for more interactive lessons!
