View a tree designed by Pythagoras. Pupils watch a video as a tree is built by using squares representing the side lengths of a right triangle, with each side of the squares becoming the side of another triangle. Learners come up with...

Fifth graders study environmental changes by examining the annual rings of a cross-section of a tree trunk. They access websites to complete a worksheet on the parts of a tree. They count the annual rings on a tree slice while observing...

Young mathematicians review fact families and create a Math Fact Family Tree. This clever lesson plan includes some excellent printouts that support the lesson.

How many trees can your pupils plant? Practice numbers 0-20 with several related activities. For the first, kids match images of trees to numbers. They then match the number symbols to number words, using a word bank. The final activity...

Choose to supplement your probability unit with this resource and you won't be disappointed with the outcome. Teach young mathematicians to organize information using tree diagrams and lists in order to determine the possible outcomes of...

Young scholars study a shopping problem. They discuss strategies for determining the number of possible choices. They create a tree diagram and an organized list. Students analyze patterns and derive an equation for the multiplication...

Students solve a story problem about how many trees can be planted in a given area. Using a map, they gather information about the size of the area and the dimensions of an acre. They use a specific equation to determine the area of...

In this word search puzzle, learners locate the names of trees. Students identify 20 names of trees. A list of names is given to assist the student in his search.

Pairs or small groups work together to determine the height of a tree using similar triangles. Learners make a judgement which direction to let a tree fall to avoid hitting any structures. They then write letters to the principal...

Learners use a ruler to make measurements, and to create triangles and a rectangle. They take the shapes they've made and assemble them into an evergreen tree image. This simple, yet effective, instructional activity would be ideal for...

In this trees worksheet, students show their understanding of measurement by solving 6 fill in the blank problems for distance, girth, and height.

In this lowest common multiples activity, students create factor trees to find the lowest common multiple of 3 numbers. Students complete 4 problems.

Find the common denominator between prime factors, factor trees, and the distributive property. Scholars learn to find the least common multiple and greatest common factor of pairs of numbers. They rotate through stations to connect...

In this tree diagrams worksheet, students draw a tree diagram to represent a given situation. They identify the total number of outcomes. This one-page worksheet contains 5 multi-step problems.

Measure a tree? Yes, measure a tree! Students get outside and measure a tree's trunk, crown, and height. Each group compares their answers to determine if any re-measuring is necessary. Once back in the classroom, students make bar...

Finding the prime factors of two numbers is the focus of this math instructional activity. Students write the factors to complete 2 factor trees, write the prime factorization for 9 numbers and answer 2 word problems.

Show how to factor four different numbers using a factor tree. This short slide show defines factoring and then shows how each number 28, 32, 33, and 30 can all be factored. 

For this LCM worksheet, students use work space provided to create factor trees and find the LCM of sets of numbers. Answers are included on page 2.

Learners examine and discuss prime numbers, composite numbers, and prime factorization. They develop and create a factor tree mobile using exponents.

In this combinations and probability worksheet, middle schoolers solve 3 short answer problems. Students draw tree diagrams to represent possible outcomes in a sample space. Middle schoolers determine the probability of an event.

In this counting learning exercise, students count the Christmas tree items on the Christmas tree. Students count how many candy canes, hearts, bows, and balls there are on the tree.

In this counting Christmas trees worksheet, students practice counting from one to five by counting each of the Christmas trees out loud on the worksheet.
