In this number sense and operations learning exercise, learners solve 15 different types of problems that include reading number lines and solving inequalities. First, they write the scientific notation of various numbers given. Then, pupils write an expression that contains only positive exponents. They also solve an inequality and graph the solutions on a number line.
Learners solve word problems using number sense. They convert fractions to decimals and mixed numbers. Pupils determine if a given fraction is greater or less than another fraction, and order numbers on a number line.
Seventh graders practice the concept of estimation and number sense using Java applet. They demonstrate skills in addition, multiplication and percentage computations. After reviewing a variety of estimation strategies, they play a java-based game using applets on computers.
In this number sense and operations activity, 7th graders solve 15 different types of problems that include estimation and expanded notation. First, they simplify various equations by following the order of operations. Then, students write numbers given in expanded notation. They also estimate the difference in problems.
Students practice number sense strategies. They estimate the sum, product and percent of two, three, and four-digit numbers. Small groups of students use computers to play java-based games.
In this number sense worksheet, students solve and complete 20 different problems. First, they write each decimal in words and then write the correct decimal in number form. Then, students write each number in scientific notation and put the numbers in order from least to greatest. They also write the equivalent fraction in lowest terms and the equivalent decimal for each.
Second graders complete math activities including patterns, number sense, operations, geometry, and more. In this math lesson plan, 2nd graders play games such as "Eyes have it", and "The shape of things" to learn these concepts.
Learners develop number sense through a change in approach to the teaching and learning of mathematics. This approach focuses on students and their solution strategies rather than on a
And they're off! Working in pairs, young mathematicians roll dice to see who can fill in their double ten-frames first. When students finally fill in their arrays, they create addition number sentences that represent their rolls, helping to reinforce the underlying math concepts. A simple activity that offers all primary grade students an opportunity to strengthen their number sense. Perform this activity once as a whole class or as part of rotations before offering it as an option for early finishers during math lessons.
"How can you help students visualize numbers in a way that is compatible with our base-ten number system?" The answer is simple: use ten-frames. Whether they're being used as a part of classroom routines or as instructional tools, this math model offers a wealth of opportunities for developing number sense in young mathematicians. Starting with an overview of how to introduce ten-frames to your class, this teaching guide goes on to provide a list of games that can be supplemented into primary grade math lessons. An excellent resource that allows teachers to provide fun, engaging, and meaningful learning activities for their students.
Have fun while building the number sense of young mathematicians with this list of ten-frame learning games. From developing cardinality and counting skills to learning place value and basic addition strategies, ten-frames are excellent math models that support the growth of young learners. Activities that involve adult-child conversations are also included, which would work best in small group or one-on-one settings. Overall, a great set of activities to include as part of math rotations in the primary grades, or to offer as extension activities for earlier finishers.
Fifth graders explore the concept of number sense and operations as it relates to handling money. In this number sense lesson, 5th graders work with change flashcards to practice giving the correct change in a money transaction. Students then perform more difficult problems relating to money exchange.
Students estimate the number of apples in a bushel basket and complete center activities. In this estimation and number sense lesson based on the theme of Johnny Appleseed, students read about Johnny Appleseed, then estimate and count apples in a basket and solve math problems based on apples. Lesson includes extension activities and center ideas.
Students multiply and divide numbers.  In this estimation games activity, students compete with each other as they multiply and divide numbers.  They work with number sense and logic.  Students follow predetermined rules and try to become the first one to find answers in a certain range of numbers.
Learners investigate place value in base ten. In this number sense lesson, students participate in an online lesson at and demonstrate how to convert numbers from base ten to other base values.
Students use math number sense to count the number of objects in a set. They count and read whole numbers. Students use appropriate technology to enhance development of number sense. They are asked if they know what an entomologist is? Students are told that they are going to make their own bug.
Fourth graders practice locating whole numbers on a number line in this lesson. They listen as the teacher gives them directions from an included assessment worksheet. They locate the dictated numbers on their number line, and use number sense and estimation skills to solve given problems.
Using the fun Mother Goose nursery rhyme "Baa Baa Black Sheep" and the book Sheep Out to Eat, your Kindergarten class will practice number matching and will also learn facts about sheep. Beforehand, create several laminated sets of of sheep numbered from 1 to 4 and write out on chart paper the full Mother Goose rhyme. Start the lesson by either singing or listening to "Baa Baa Black Sheep," then pass out the sheep/number cards and hold up a number and have the student with the matching cards come to you. This game can be played so each young learner has the opportunity to match each number. Then continue the sheep theme by reading Sheep Out to Eat, and following having a class discussion about sheep facts. Your little learners will learn facts such as why sheep are raised and what a female sheep is called. To further recall you can prompt your learners to answer some questions about the plot of the story and how sheep behave within it. The sheep matching cards could be used in a math center with a parent volunteer. 
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 activity and notes or as a tool to build a test around.
Elementary schoolers count and order objects using numbers 1-300. They bring recyclable items from home. Students group the items, skip count by 2's, 3's, and 5's, and arrange the items on a number line. Recyclable plastic bags are put in groups of 300 to be used to make sleeping mats for the children of Haiti.
