In this online addition instructional activity, learners use the visual images to help them add the 10 addition problems. Students enter their answers in the boxes and click submit.

Math manipulatives are wonderful for demonstrating any number of mathematical concepts in a concrete and visual way. Learners review the addition property of equality and the zero property using a scale model kit (not shown). They...

Have scholars represent these fractions by drawing a number line for each. They segment the number line based on the denominator, then mark an x based on the numerator. Do one of these together before sending pupils off to do this...

Introduce scholars to addition and subtraction word problems with visual guidance. There are five scenarios here, each with a picture to guide scholars as they solve. An example encourages kids to physically interact with the images,...

Fill your mind with math as you think about filling a pool. Given information about the rates of two pipes, one filling a pool and one draining a pool, learners determine a piecewise function that models the volume of water in the pool...

Use these festive watermelon number cards as a math manipulative in with your youngsters. Laminate and cut out a set for each student to use throughout the year, or just use one classroom set for math stations. Although there isn't a...

Understanding when to divide by two or one-half can be confusing. Here is an activity that gives four different scenarios. It is up to your number crunchers to decide if they divide by two or one-half. The easiest way to approach the...

Mrs. Moore's class is trying to earn money for a trip to the science museum, but how much more do they need? Solve this problem with your own class as they develop their ability to model real-life situations algebraically. As an added...

In this Newton's Law of Cooling worksheet, students complete an essay format write up of a convection model. They write the purpose and assumptions of their lab. Students complete three rate of change problems. They describe a model in...

Small groups devise a plan to find the bag that contains the larger percentage of blue chips. they then institute their plans and compare results to the actual quantities in the bags. 

Using this resource, scholars develop graphs that model situations by showing change over time. They answer 15 questions based on information from charts that show growth in weight. They extend the concepts to an assessment section of...

What does a graph or equation say about a situation? Lots! The lesson uses the concepts explored in the previous four lessons in the series and applies them to problem solving situations. Learners create an equation from problems posed...

Young mathematicians demonstrate their ability to subtract mixed numbers by completing this collection of fraction word problems. From figuring out the weight of objects in a package, to finding the difference in height between two...

Now you can create your own monster movie. Learners estimate the size of a scale model monster given comparison statements and analyze these estimates to determine if the scale model accurately portrays a lizard.

How can you safely model exponential growth and decay? A hands-on activity uses candies to model not only exponential decay, but also exponential growth. Exponential equations are fitted by hand and by use of a calculator...

Fraction models are a great way to help scholars visualize this concept, and they focus on thirds with these practice problems. First, there are five shapes each segmented into three even sections. Learners color in one-third of each,...

Represent fractions visually using shape models. Scholars color in two sets of shapes to represent specific fractions: 2/3 and 3/4. The shapes are segmented into equivalent fractions for most of these, so scholars need to understand this...

Modelling fractions through shapes is a great way to demonstrate this concept to beginners. Learners examine 12 shapes, each divided into an even number of equal segments (up to 16 parts). They shade in half of each shape by shading half...

What fraction is represented by these shapes? Scholars examine fraction models as they apply basic fraction skills. The first two problems are guided; they look at a set of shapes with some shaded, circling (from three options) the...

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...

It's the stairway to learning! Scholars research all aspects of building a staircase. Using information from building codes, they write and graph a system of inequalities to analyze the constraints. The completed project is a scale model...

Use an inverse linear function to interpolate a point. Presented with the number of households over a period of year, pupils find a linear function that will be a model. Class members determine the inverse of the linear function and use...

Class members investigate how positive and negative numbers are useful in the real world. Individuals first read a short passage and identify terms indicating positive and negative numbers. They consider situations involving positive...

The process of elimination really works! Use elimination when substitution isn't doing the job. The 29th segment in a series of 33 introduces the elimination method to solving linear systems. Pupils work several exercises to grasp the...
