Math Games for Number Sense One Through Three
Learners use manipulatives to play math games. For this number sense lesson, students participate in counting, matching, and adding games. Learners understand the directions for each game.
Prime Numbers and Prime Factorization
Clarify prime numbers, composite numbers, and prime factorization with this worksheet. After looking over definitions, working through prime numbers, and making composite numbers, learners are introduced to prime factorization and the Sieve of Eratosthenes. This resource includes a homework assignment in which mathematicians respond to 7 short answer questions that ask them to solve, identify, and explain mathematical concepts in their own words.
Those Numbers Aren't Just Moody. They're Completely Irrational!!
Which numbers are rational and which are irrational? Play an initial speed round with a linked online game to see where kids are at with this concept (you should have already covered it at the basic level). Challenge scholars to consider how to graph irrational numbers (think about the fact that they never stop). The linked online explanation does a great job of illustrating this concept; however it is extremely text-heavy so you may want to address this yourself. Next, give kids some guided practice. You can use the online problems or the attached worksheet. Consider having kids go back to the original fast-paced online game to see if they improve. The "First Million Digits" link is interesting if you have some extra time, but the remediation links may not operate.
Dividing Whole Numbers by 5
Solve division problems by using strategies with your class. Scholars will explore how to divide whole numbers by 5. They perform guided practice worksheets and play whole class games to practice this skill. This lesson includes worksheets, an evaluation, and an assignment and is 5 pages long.
Turn your math lesson into a carnival game with this fun, outdoor activity. After reviewing the concept your class will be practicing briefly, split your class up into teams and head outdoors. These teams work to solve math questions and are rewarded for each right answer by popping a balloon filled with prizes! Although this lesson uses word problem involving the basic operations of adding, subtracting, multipling, and dividing, this motivational activity could be adapted for any material.
Partitive Division: Sharing Cookies
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 listen to the book Five Little Monkeys Sitting In a Tree, identify written numbers 0-9 and the symbol for subtraction; students subtract two single digit numbers using manipulatives, and recite the corresponding number sentence.
Grade 3: Palindrome Patterns
Third graders use addition to create numbers that are palindromes and organize their results to look for patterns. They make generalizations from patterns and practice reading large numbers and addition with regrouping.
The Math Star Wins the Cup
Students recognize and count numbers 1-4 using a racing game. In this math lesson, students move cars around a racetrack by matching colors and seeing numbers. The student who finishes the race first is the winner.
Using Percents in the Real-World
Seventh graders use a variety of strategies to solve problems with integers, fractions, decimals, and percents. For this number operations lesson, 7th graders discuss sales tax and use grids to represent money and percents. Students shade in the grid to solve percent problems. Students solve sales tax, discounts, and sales price percent problems. Students improve reasoning skills and visualize real world percent problems with the grids.
It Has Been Rubbish For Years
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.
Students in second grade are paired with fifth grade computer research buddies. They observe the characteristics of caterpillars, and identify the four stages of the caterpillar to butterfly life cycle. They graph the number of butterflies that hatch from chrysalis over the course of a week using web resources. They design a PowerPoint presentation.
Grade 2: Exploring Place Value
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.
Grade 5: Multiple Towers
Fifth graders use interlocking cubes to build towers to represent factors of numbers and place the towers in the appropriate places on a Tower chart in order to look for patterns. They work in partner groups, and finish by writing statements about prime numbers, composite numbers, and patterns they noticed during the activity.
Johnny Appleseed Walkabout
Second graders calculate mileage for a journey. In this place value and measurement lesson, 2nd graders read Johnny Appleseed, work in groups to locate his birthplace on a map, locate the other states he stopped in, and measure the distance between each stop. Students calculate the mileage needed for Johnny Appleseed's journey and discuss the place value of each number.
Grade 3: Make a Hundred
Third graders roll a die seven times, each time determining whether to add that number of tens or that number of ones to try to make a sum as close to 100 as possible without going over.
First graders are introduced to addition with the help of the book, "So Many Cats," by Beatrice Schneck de Regniers. They practice whole numbers by counting cats in a story and in pictures by identifying, and comparing whole numbers as well. Each student recognizes that addition is the progressive accumulation of a given object.
Shel Silverstein Poetry Math
Fifth graders complete math computation with Shel Silverstein poetry. In this poetry instructional activity, 5th graders listen or read certain poems that have numbers in them. They add up the numbers throughout the poem and answer other math related questions.
Complex Numbers (Part 1)
In this video, a complex number is defined and graphed on the complex plane. Sal also shows how to add, subtract, and multiply two complex numbers. He starts showing how to divide two complex numbers, but runs out of time and continues in the next video.
Domain: Operations and Algebraic Thinking
Practice basic operations for young mathematicians in fun ways! Using two decks of cards (Ace through 10 plus the joker), learners play "memory" by matching numbers that can be added to make 10 and writing number sentences. In another game, scholars examine clear bags with small items to determine how many more would be needed to make 10. They can use missing addend sentences and search for other groups whose bag has the needed amount to combine! A word problem is also included.
