Math Without Tricks: Making Sense of the Division of Fractions
The "Keep-Change-Flip" (KCF) method is a common math trick used to teach students how to divide fractions. The instructions are simple: keep the first number, change the division sign to multiplication, and flip the second fraction. This method works and provides the correct answer, but there is a significant downside.
If our only focus is on getting the answer, KCF can seem very appealing. However, students often end up with no clue how they arrived at that answer or if it even makes sense. Additionally, tricks without meaning are frequently applied incorrectly in later problems, leading to confusion and errors.
I am a strong advocate of helping students understand that math makes sense. I'll show you a way to approach fraction division that gets students thinking critically and making sense of their answers.
5th Grade Math Classroom Decorations and Back to School Ideas
The beginning of the year is the time to get to know students and let them know what they can expect for the year. Engaging students and learning about their interests the first day can get the year off to a great start.
I’ve gathered some of my favorite resources for back to school. Included are ideas to set up your fifth grade math classroom to be an inspiring setting for learning, activities for the first day, and routines we can establish from day 1.
