Improving Measurement and Geometry in Elementary Schools
Rep Tiles
In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...
Curated OER
Reflections
Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...
Curated OER
Area Adventure
Learners calculate the area of figures using the formula: length x width = area. They solve area problems using paper squares, geoboards, and real-world problems.
Curated OER
Tick Around the Clock
Students examine and discuss the differences between clocks they are shown. Using the internet, they research how people used to tell time before clocks. They review what the long and short hand on the clock represent and practice...

The Sum of the Interior Angles of a Polygon
Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this lesson.

Minnesota-China Connections:What Time Is It?
Students calculate the time difference between Beijing, China and their local community. They discuss how time difference affects intercultural communication.
Curated OER
Box and Whiskers
Middle schoolers discover how to relate collected data with a box and whiskers graph in a number of formats. They collect, organize, create, and interpret a box and whiskers graph. Pupils interpret the difference between sets of data,...
Curated OER
Rep Tiles
Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...
Curated OER
Tomb Robbers
Sixth graders identify benchmark angles as they are embedded into a circle grid. They observe the teacher using an angle ruler and complete a Star Spangled worksheet, play the game Tomb Robbers, and as a class discuss their game winning...
Curated OER
Tomb Robbers
Sixth graders examine benchmark angles embedded into a circle grid and examine how grid systems do not always have to be square. the game "Tomb Robbers" is used to develop strategies.
Curated OER
Making Benchmards--Length
Students explore the idea of having Benchmarks to estimate the length of given objects. Students demonstrate acquired knowledge of the basic units of length by making reasonable estimates. Students create a personal benchmark.
Curated OER
Scaling Our School
Fourth graders practice estimating the length and height of buildings at their school. They then compare their estimations with the actual heights or lengths. Each student then builds a scale model using ratio to translate the "real"...
Curated OER
One Size Fits All?
Learners describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They also...
Curated OER
Relationships and Functions
Fifth graders describe patterns as relations and functions. In this patterning lesson, 5th graders analyze and continue patterns. Students understand how patterns relate to relations and functions.
Curated OER
How Fast Is Fast?
Students make sensible estimates and check the reasonableness of the answers. Students write and solve problems involving decimal multiplication and division. Students perform calculations with time.
Curated OER
Introduction to Hours & Minutes
First graders identify, interpret, and gain proficiency in using a clock to tell time to the hour and determine how many minutes are in an hour. They identify and list what they do as they travel through their dayand how much time you...
Curated OER
Making Change
Second graders explore how to incorporate a new type of technology, the cash register and/or a calculator, as a motivational tool for solving real life problems. They practice estimating money and counting back change from $20.00.
Curated OER
Time: Attribute
Students participate in five teacher-led, whole class activities that explore sequences of time and the concept of faster and slower. They sequence school day events, create a book of their daily schedule, put the days of the week in...
Curated OER
Rice (Gohan) Observations
Second graders investigate rice or gohan as it's called in Japan in a couple of experiments. They tally the results.
Curated OER
Car Maze competition
Learners use graphs to calibrate an RCX car. They must then program the car to traverse a maze using their calibrations
Curated OER
Shadows
Learners conduct an experiment. In this shadows lesson, students record the height of a meter stick. Learners then cast shadows and record their length. Students compare the length of the shadow with the actual height of the meter stick.
Curated OER
Get the Turtle to the Pond
Students solve problems. In this math lesson, students write solutions using LOGO commands in order to help get the turtle to the pond.
Curated OER
Heavy Ice: Day Five
Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...

The Home Stretch
Students read the novel Stone Fox by John Reynold Gardiner. Using Lego RCX units, students build and program sleds to re-enact the "home stretch" of the National Dog Sled Race.
