This is a geometry project for middle school students - 6th, 7th, and 8th graders. Students use containers - boxes and cans/cylinders to calculate surface areas and volumes. The containers can be brought from home or found other places. This can be used as a cooperative learning activity or as individual work. Standard, metric, or both measurements can be used for calculation purposes. Estimation techniques can taught and practiced. Extra work is included if needed. This can be a one day project or spread over several days.
Does not apply
Solve real-world and mathematical problems involving the four operations with rational numbers.
Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.
Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. For example, create a story context for (2/3) ÷ (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) ÷ (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (𝘢/𝘣) ÷ (𝘤/𝘥) = 𝘢𝘥/𝘣𝘤.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi?
Know the formulas for the volumes of cones, cylinders, and spheres and use them to solve real-world and mathematical problems.
