### How Does the Cookie Crumble?

Students will self-discover how to multiply mixed numbers by using background knowledge of estimation, computations, and real world application of a recipe.

Texas Essential Knowledge and Skills Related to the Unit

In fifth grade, students will be able to multiply and divide whole numbers, which will lead into multiplication and division of decimals in sixth grade. That same year, they will model products and quotients of decimals to the hundredths place. This concrete model will lead them to a better understanding of the algorithm in fifth and sixth grade.

As fifth graders, students will model multiplication and division of a fraction and a whole number. The following year, students are expected to multiply and divide all types of fractions.

In addition, during sixth grade, students are introduced to integers (negative whole numbers) and will be able to model and solve all operations with integers. All of the skills previously stated will lead students to be able to perform all operations of rational numbers without models (positive and negative fractions, decimals, and whole numbers) in seventh grade.

### Save the Factory!

Students will design an experiment to test the outcome of friction in force and motion. The students will create an inclined plane demonstrating their knowledge of mechanical energy and the effects of gravity on an object. Students will use previous knowledge of friction to complete their task of stopping their object. Critical thinking skills will be the focus of the lesson as students will have to utilize their scientific problem-solving skills to make decisions regarding their experiment.
