We Are Teachers – Erin Bittman
Make exploring math concepts—including multiplication and place value—fun for students using Lego bricks. Here are some ideas.
Lego Fractions
Give students 10 Legos of various colors. Students stack their Legos, then they figure out the fraction for each color. This can also be turned into a math game (image below). Students roll a die and create Lego fraction towers, then they figure out the fraction.
Lego Area and Perimeter
Students can create big areas by putting Legos side by side, or find the area of single bricks. They simply count the studs on top of the bricks. Students can also find the area and perimeter using grid paper. Tell students not to stress if bricks don’t fit perfectly on the grid paper. They can round up. Have them color the area of each of their Legos on their grid paper.
Lego Tech Integration (Area and Perimeter)
Build with Chrome: Students find and explore different plots. They can re-create a famous landmark or just play around. Once they are finished building, they can print their creations and find the area and perimeter of their structure. 3-D or 2-D versions of the art can be printed out.
Lego Multiplication: “Groups of” and Arrays
Groups of: Make multiplication fun with Legos! A Lego brick represents one group. Kids count the studs to figure out the multiplication equation. For example, 2 lego bricks with 4 studs (2 groups of 4) is 2 x 4. Then, they solve it. (2 x 4 = 8).
Array: When you look at the studs on top of a Lego, you see an array. Kids examine the rows to figure out the equation. For example, one Lego brick with 8 studs (2 horizontal rows of 4 studs, 2 x 4 = 8).
Lego Mean, Median, Mode and Range
Hand each student a baggie of various Legos and explore mean, median, mode and range!
Array Studs
1. Have students classify bricks by number of studs.
2. Then, have them figure out the total number of studs for each group.
3. Once they have their numbers, they figure out the m, m, m, r.
Number of Bricks With Same Number of Studs
1. Students classify bricks by number of studs.
2. Then, they count how many they have in each group.
3. Then, they figure out the m, m, m, r.
Lego Colors
You could also build Lego Towers and classify bricks by color. Then, have students figure out the mean, median, mode and range. Set a timer and have kids build the tallest tower they can before the time runs out! They take their tower apart and classify their bricks by color. Using their data (ex: 19 red, 10 blue, etc.), they figure out the m, m, m, r for their Lego colors.
