I present you with an introductory lesson on Formulas! Your students will enjoy manipulating the variables in our lesson from one side of the equal sign to the other, depending upon the problem at hand. Formulas presented in the lesson are for Celsius and Fahrenheit conversions, Kelvin and Fahrenheit conversions, area of triangles, area of rectangles, density and mass, the distance formula, and simple interest.

These Area and Perimeter Posters are useful visual reminders for students…

Looking for a way to give your students additional practice with area and perimeter skills? This set of 20 cards increases in difficulty throughout the set. The first cards involve counting squares to find area and perimeter. As the set progresses, students use the area and perimeter formulas to solve “open” rectangle problems. Finally, the last 8 cards have “irregular” shapes that require students to either decompose the shape into smaller rectangles. Use as a math station…as a class…

4.MD.3 - Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.

Area of Rectangles Digital Interactive Notebook is a Digital Interactive Notebook Resource to be used with Google Slides. Students work with the area of rectangles formula through notes, guided practice, and individual practice. Only whole numbers are used in this product.

This product consists of (8.5x11-size) design posters of the area of a rectangle formula, area of a triangle formula, area of a parallelogram and plain posters for each of the formulas. The design posters were created to be colored, and the plain posters are available if a student chooses to create their own design.By coloring or drawing these posters, the student will better memorize/learn the formulas.

Nets and Composite Figures. In this collaborative activity, students find the areas of nets (rectangular prisms, triangular prisms, square pyramids, triangular pyramids) and composite figures that are made of rectangles and triangles. There is no need to know the formula for the area of a trapezoid to compute any of the areas.

Help students discover the area of a triangle by cutting a triangle and fitting it inside of the rectangle it is half of, allowing them to discover the formula on their own. Tell them the formula and they may forget, let them discover it and they will remember it through their self-discovery! This product contains various triangles, starting with the simple right triangle and extending to the more challenging scalene triangle. Then use the task cards in small groups or in a game of scoot.
