Estimating is an essential skill used in everyday life. This presentation explains how to apply prior knowledge about rounding numbers to estimating sums and differences. Example problems and assessment include large numbers, making this...

Reinforce estimation and the four operations—addition, subtraction, multiplication, and division—with eight page, 15 problem independent practice exercise.

Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math lesson. Using the coding formula listed, children learn to fluently estimate and calculate...

A set of third grade math vocabulary cards include topics that range from addition properties to terms like estimate and fact family. Each sheet has two cards on it. The top half is the word printed in bold text,...

Develop young mathematicians' ability to compare fractions with investigation into the number 1/2. After brainstorming a list of fractions equivalent to 1/2, children identify a pattern in the numerators and...

Help pupils explore estimation. They will make estimates and discuss when you might use an estimate. Then they discuss if their estimates are reasonable.

First graders practice rounding 4 digit numbers using place value concepts. In this estimating sums and differences lesson, 1st graders explore clustering, rounding, and front end estimation as methods for rounding decimals.

Pupils use mental math. They describe reasonable and unreasonable sums and differences. Students use mental math to find the sums and differences of addition and subtraction facts at random. They solve addition and subtraction facts...

Students explore the concepts of estimating and rounding. In this estimating and rounding lesson, students play a game of tic-tac-toe. Students pick items and must estimate their cost by rounding. Students estimate the costs of pretend...

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

Young scholars develop their own strategies to solve basic addition and subtraction facts. In this addition and subtraction lesson plan, students use strategies they already know and new ones to solve problems.

Young mathematicians explore two-digit subtraction. They will investigate multiple ways to subtract numbers involving regrouping. Resources are provided.

First graders make sensible estimates and check the reasonableness of answers. They make up, tell and record number stories up to 9 about given objects. They skip count in twos, threes and fives.

Second graders become familiar with need strategies for computation of money problems and estimating sums. In this computation lesson, 2nd graders solve real life problems to understand estimation and money problems.

For this quadratic formula worksheet, students solve and complete 22 different types of problems. First, they solve each equation by completing the square and applying the quadratic formula. Then, students graph each function provided...

Students determine how to make the largest sum of money using the least amount of coins. In this mixed currency lesson, students listen to a reading of If You Made a Million by David M. Schwartz before participating in money counting...

Students discuss jettons and their archaeological importance at Jamestown. They then practice using historic counting sheets and artifacts to understand the calculating methods of the early 17th Century, and identify their similarities...

Learners practice finding the sums of two-one digit numbers. In this addition lesson plan, students also record facts onto an addition chart.

High schoolers calculate the area under a curve. In this calculus lesson, students integrate the function to find the area under the curve. They use the Ti to create a visual of the graph.

Students collect experimental data and record it on a frequency table. After accessing an Internet coin toss simulation site they discover that repetition of an experiment may result in different outcomes. They identify the mutually...

Students select and use appropriate operations, methods and tools to compute or estimate using whole numbers. They develop and use formulas for determining the circumference and area of circles. Students determine and describe the...

First graders study number pairs and identify number pairs that sum to numbers from 10 to 30. They use number pairs to solve addition and subtraction problems. They make sensible estimates and check the reasonableness of answers.

Students explore mathematics by participating in a group activity. In this number value lesson, students identify the uses for decimals and how to best estimate whole numbers based on decimals and fractions. Students collaborate with...

Young scholars review for the Regents Exam. In this math lesson, students review core concept for the Regents exam by working a variety of problems. A printable worksheet is provided.
