Curated OER
Teaching Students Mathematical Reasoning Skills
Students can build upon their basic math skills and become higher order thinkers when we encourage the following principles.
Curated OER
Equivalent Fraction Paper Strips
Young learners compare the relative values of fractions by making physical representations. They fold and label strips of paper that are equal in length to represent "one whole" and the equal parts that fractions represent. Also, they...

The Road to Proportional Reasoning
Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

Ratio and Proportion
Do these items have the same ratio? Through a learning contract, pupils master proportions by practicing proportions via word problems, graphs, and with manipulatives. An exit ticket checks for understanding at the end of the...

Constant Rate Exploration
Question: What do rectangles and bathtub volume have in common? Answer: Linear equations. Learn how to identify situations that have constant rates by examining two different situations, one proportional and one not proportional.

Solving Linear Equations
To find x, you have to get it by itself, correct? Individuals solve a linear word problem and share their solutions with others that solved the problem in a similar fashion. They then complete a self-assessment on how they feel about...

Poly-Mania
This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Yum Yum Cereal
Design an efficient cereal box. Scholars use set volume criteria to design a cereal box by applying their knowledge of surface area to determine the cost to create the box. They then determine whether their designs will fit on...

Dandy Candies
Package design is an economic necessity. Young scholars assume the role in an interesting inquiry-based lesson. Given 24 cubic shaped candies to package, they must determine the arrangement that uses the least amount of cardboard to...
Curated OER
Subtraction Shopping
Students subtract two digit numbers. They check each other's answers for accuracy.

Graphing Data
Students graph lines in a coordinate plane. In this geometry instructional activity, students graph lines on a coordinate plane, and identify the slope. They calculate the volume, area and perimeters of the shapes created on a coordinate...
Curated OER
Collecting Data and Graphing
Young mathematicians collect data and graph it. They work collaboratively to collect data regarding the span of arm length versus height and graph the data they collect.

Lesson 10.2 Volume of Prisms and Cylinders
Tenth graders investigate volume in class and in the real world. They explore volume of cylinders and prisms as it relates to different subjects. Pupils also investigate how important volume is in different career field.

Area And Perimeter Using Pentominoes
Third graders engage in an enrichment lesson exploring the concepts of area and perimeter. They construct new pentominoes that are 3 times the size of normal ones and then identify the area and perimeter measurements. They then create a...

It's About Time
First, second, and third graders explore elapsed time through estimation and prediction. They work with a partner to estimate how long it will take to perform various tasks. One person uses a stop watch to time his or her partner...
Curated OER
Odd and even
Learners play a game requiring them to select groups of odd or even numbers of objects with the aim of reaching a total which is an odd number. They carry out a more formal investigation of patterns in additions of odd and even numbers.

Linear, Square, and Cubic Units
Linear, square, and cubic units are all investigated as different types of packages are measured. The teacher will need supplies such as a box of aluminum foil, a package of ribbon, and a bag of mulch. The class determines the...

Cuisenaire Mats
First graders use Cuisenaire rods to study the mathematical symbols =, <, > for the relationships is equal to, is less than, and is greater than. They use the rods to show visual explanations of common number combinations.

Castles On The Ground (2D & 3D Shapes)
Explore the relationship between 2D and 3D shapes by having your class view representation of shapes and investigate their symmetry. They will create a solid object from diagrams and describe the reflection or rotational symmetry. In the...

Numbers Are Made of Parts
Children play with barnyard animal cards to practice composing and decomposing numbers. With their "secret number" of animal cards in a cup, they shake and spill them onto a barn story board, counting how many animals fall in the barn...

Measurement (Grades 3-5)
Third, fourth, and fifth graders participate in measurement centers. They visit six different centers: standard and linear measurement, clocks, weight, volume, temperature, and converting measurements. They complete a data collection...

The Roll Out Fractions Game: Comparing Fractions
Reinforce the concept of comparing fractions with a hands-on, two-player game that calls for a visual model, score board, and dice. Players roll dice to acquire their given fraction, create the fraction using fraction tiles, then...
