Make young mathematicians' dreams a reality with this fun drawing project. Given the task of designing their dream home, students create drawings and physical models that demonstrate their understanding of proportion and scale.

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.

Favorite family recipes and cuisenaire rods are used to help learners understand fractions. They bring in recipes from home and then use their cuisenaire rods to model the fractional values needed to prepare various dishes. A great way...

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...

Your geology class practices taking core samples of a potato to examine the stratigraphy. This is a terrific modeling lesson that helps youngsters visualize strata that cannot be seen from the surface of the ground. The directions...

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...

Explain algebraic relationships through an understanding of area and perimeter. Continuing concepts built in the third instructional activity of the series, the fourth installment of 28 asks learners to identify common expressions...

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...

Find the math in recipes. Young chefs will follow a recipe and investigate the total cost for materials. They measure amounts of food necessary for the recipe and compute the per person cost.

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...
