Here is an extensive set of teacher's notes to help you teach all about integers. Begin by introducing a number line and how it can be used to visualize positive and negative numbers. Talk about absolute value and the additive inverse concept. Finally, instruct your class about applying all four operations to positive and negative integers. Whereas there is nothing out-of-this-world in this resource, it is comprehensive and especially helpful if you are new to teaching these concepts!
If your second-graders are learning about place value and number value comparisons, this set of engaging activities and worksheets will make your job easy!  Scholars use math manipulatives to estimate and then determine how many seeds a colony of Harvester Ants have gathered. They estimate the total number of sticks in a container, grouping them  in 100s, 10s, and 1s to make counting faster. Students also play math games during which they analyze three-digit numbers to 999. These six activities have students competing, moving, thinking, and having fun. Every print-out you will need is included.
Bring some sweet fun to your math class (you can use sugar-free cookies also)! Pupils practice division and remainders with the assistance of a bag of cookies as manipulative's to assessing the concept of whole numbers. In groups, they create their own division problems that they eventually present to the rest of the class. Great ideas are presented.
Students are presented with the problems of percentages and focus upon numbers in contrast to 100. They calculate problems with money and are engaged with the use of games as a teaching tool. Students also interpret data as presented in a graph.
This number sense and operations study guide provides notes and explanations as well as practice problems. In order to practice their math skills, learners write fractions as decimals, identify which number set a number belongs to, take square roots, and change decimals into rational numbers. This could be used as stand-alone instructional activity and notes or as a tool to build a test around.
Here is an excellent lesson on fractions, decimals, unit rates, proportions, and problem solving. In it, learners engage in six activities in an "investigation center." The activities are based on a fictitious trip to a bakery, and involve several important concepts of rational numbers and proportions. Outstanding blackline masters are embedded in the plan, which will make it easy to successfully implement the lesson with your class.
Creative problem solving is fun and helps kids conceptualize content. They use grid paper, manilla paper, and markers to cut, draw, and show given double-digit numbers as many ways as they can.
Students practice the skill of skip counting. For this early math lesson, students try counting at different rates, beinning at one and progressing to the number ten. Students create a number grid with Crayola Crayons.
Middle schoolers practice solving equations adding decimals and integers. Using a worksheet, they identify which pair of numbers goes correctly with the problem. They review their answers and are graded based a rubric given to them.
Students practice assessing their TI-15 calculators to reinforce their skills in integers, fractions, decimals and operations to the finding of mathematical expressions that equal 100. They display examples of addition, decimals, subtraction, fractions, multiplication, etc.
In this order of operations worksheet, students solve 16 problems in which order of operations rules will be used. No examples of PEMDAS are given. All four number operations will be needed.
Students explore two different models to assist them in developing the meaning of integers. They examine ways of representing numbers, relationships among numbers as well as number systems. This task is scheduled to be completed in the computer lab.
Young scholars investigate the patterns formed by remainders in whole-number division with their TI-15 calculators. They practice reviewing and analyzing data as well as drawing conclusions on all the whole-numbers that occur more often than others.
Students use a number line to assist with their additions. They use a calculator to check for factors. Students are taught factors and multiples. They use array model of multiplication to define meaning. Students develop a wide range of adding, subtracting, multiplying, and dividing strategies.
A series of engaging activities gives second-graders practice with three-digit numbers up to 1000. They examine three hundreds charts, one with numbers 101-200, another with 901-1000, and a third counting by 10 to 1000. Worksheets give independent practice on this skill and ordering numbers from least to greatest. Next, learners try to guess the "secret number" on a number line using greater-than/less-than clues. Several worksheets are included here for practicing these skills in fun ways.
What a fun set of math operations activities! First, the mysterious Digit Switcher writes letters to your first-graders, challenging them to recognize patterns in three-digit numbers. Then, the class works together analyzing three-digit numbers in a pocket chart. Lastly, learners complete facts by filling in a number greater than x and less than y. A letter is included to send home to families requesting they find a three-digit fact for you to use in the classroom.
Explore scientific notation in this mathematics lesson. Young mathematicians explore multiple representations of large number in scientific notation through the use of models, visual representation and expanded form. The lesson provided for flexible grouping options and addresses various learning styles. They work in groups and discuss the following questions: Why do we use scientific notation?, Who uses scientific notation? What does a nonzero number raised to the zero power equal? Why? and What is meant by the power of 10?
"Teens in the red" is a growing group. Help youngsters avoid future credit card debt by teaching them about interest. Two tasks involve the use of credit to give your class practice solving multi-step math problems by applying properties of operations. Hopefully they learn not only how quickly interest piles up, but also to avoid becoming one of the statistics!
Preteens create a foldable in order to review the properties of operations. They apply their knowledge to write equivalent equations using stock market scenarios. A neat homework page is provided that has four expressions to be simplified using the distributive property, as well as a few word problems to solve. This lesson succeeds in addressing the Common Core standard that it was designed for. 
Bake-up some cookie fractions with your class in order to determine improper fractions and mixed numbers. Young bakers calculate cookie orders given on an order form. From their calculations, they write the improper fraction, mixed number, and total amount of whole cookies ordered. Class members then confirm the orders on a confirmation form and code it accordingly. The task may be introduced to the class with the story The Hershey's Milk Chocolate Fractions Book by Jerry Pallotta. A fun and useful way to visualize mixed numbers!
