There are a wide variety of manipulatives that teachers and parents can use to enrich math lesson plans, games, and activities. Lego bricks are a great option. From patterns to adding to graphing, there are methods for incorporating Legos into math lessons for virtually any level of grade school. Don't forget to consider using Legos to expand simple worksheets and printables as well. A simple manipulative or two can make all the difference between an okay lesson and a great lesson.
FYI: The knobs on a LEGO brick are called studs. They are referred to as such in this article.
Most of the linked lesson plans and other materials are geared toward special age groups or skill levels. Don't feel limited to this. Many of the activities here can be modified or adapted for multiple groups.

 Double Digit Addition and Subtraction {with Lego Bricks}
Use your Lego bricks as a handson way to teach kids how to add and subtract double digit numbers with remainders.  Lego Math (Free Add. & Sub. Worksheets)  Squarehead Teachers
Addition / Subtraction
Add Lego bricks or the studs on the bricks. Many students benefit from learning the concept of "adding on" in order to grasp the concept of addition. Legos are a great supplement for any "adding on" lesson. Consider the colors of the Legos for any addition or subtraction lesson. Students may benefit from distinct color groups for different numbers (i.e. adding four red blocks and six blue blocks).

Counting
In addition to simply counting individual bricks, students can count the number of studs on the bricks. Legos are also a great tool for practicing counting by groups of 2, 5, 10, and more.
Alternative: Consider dedicating a small group of Duplo blocks for math activities. Label one side of each block with the number and another side of each block with a set of dots to represent that number. Can students count the dots? Can they order the blocks correctly? Check out the link to the right from The Imagination Tree for more ideas for these blocks.
Estimation
Create groups of Legos and have students determine which group has approximately X number of Legos. Check the guesses afterward and compare the numbers.

 Using LEGO to Build Math Concepts  Scholastic.com
Here are some of the many ways that I use LEGO to boost engagement while introducing my students to a wide range of math concepts.
Fractions
You can build stacks of Legos to work on any number of different fractions. It is important to consider the color choices for the stacks (i.e. one half of the stack is red, one half of the stack is blue). As students become more comfortable with the concept, it may be appropriate to ask them to break stacks into fractions (i.e. divide the stack of Legos in half) without any relation to the colors at hand. Legos also lend themselves to the concept of "how many parts make a whole?" which can be a great component of a fractions lesson.
Geometry
Legos are great tools for teaching area, perimeter, and volume. Consider taking Lego base plates in different sizes and having students calculate the area and perimeter for each. You can also use Legos to construct your own squares and rectangles for calculating area and perimeter. Build Lego stacks in varying heights and thicknesses for students to calculate the volume. Consider complex shapes that may require students to break down the individual pieces in order to calculate area, perimeter, and volume.
Graphing
You can incorporate Legos into virtually any graphing lesson plan that involves manipulatives. Instead of using cube blocks to build graphs, students will enjoy the change of using Lego blocks.
Math Terminology
Legos can be used to supplement lessons and activities pertaining to any of the follow math terms:
 Above / below, over / under
 Before / between / after
 Equal / unequal
 First / last
 Greater than / less than
 Left / right
 Long / short
 Mean, median, mode, range
 More / less
 Ordinal numbers (first, second, third...)
 Similarities / differences
 Small / large
 Spacial relationships (i.e. is the small block on the top or the bottom of the stack?)
 Top / middle / bottom

Measurement
One of the standard components in any measurement unit is nonstandard measurements. Legos are a great option. Use Legos to measure various objects around the classroom. Then challenge students to find objects that match the length of given Lego stacks.
Multiplication in Kindergarten using Lego blocks
Multiplication
Lego bricks lend themselves naturally to multiplication as students can multiply the number of studs on one length by the number of studs on the other length of a given brick. To make larger bricks, simply lay bricks right next to one another on a table or other flat surface.
Patterns
Create patterns with Legos and have the students extend the patterns or copy the patterns. Give them the opportunity to create their own patterns as well.
Shapes
Can students tell the difference between the square Legos and the rectangle Legos? Discuss their similarities and differences. Are there other shapes that you can build with Legos? Lay them out on the floor to build triangles. Can students build different types of triangles (i.e. right, isosceles)?
Sorting
Sort Lego bricks into different groups by color, shape, size, or number of bumps. Can the students name the colors or count the numbers? Discuss how the sorted groups are the same and how they are different. If you are doing a color sort, can the students pick out the primary colors?

Weight
You can use a kitchen scale or a postal scale to measure groups of Lego blocks in ounces and pounds.

Yayso glad to see this great resource! :) Will be sharing it with others and pinning to my Home Ed board, and most of all, I hope to do some of these lego math activities with my grandchildren one day. Linking it to my hub on gift ideas for kids, too.
Neat! Playing with LEGOs is a great way to develop intuitive problems solving skills.
Very good job! I have also written in behalf of these great colorful plastic little things. Great to know about this hub, very complete and informative.
I love Legos! What cool ideas! Fun ways to learn are the best. :)
Shared with my daughter on facebook. Her 7yearold has discovered the wonder of legos!
Great ideas. Can be very useful!
