Students add numbers to ten.  In this addition to ten lesson, students play the Ten frame interactive game to learn about addition and facts to number ten.

Developing fluency with basic addition and subtraction is fundamental to the success of all young mathematicians. This four-day lesson plan series begins with learners using ten-frames and hundreds charts to recognize patterns when...

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...

How many people and animals can cram into a single bed? Find out with this cross-curricular math and language arts lesson. Following along with a reading of the children's book The Napping House by Audrey Wood, young mathematicians...

Learning to break apart numbers into smaller pairs is a critical step young mathematicians take as they develop their number sense. To practice this skill, children are provided with sets of three numbers and are asked to pick the two...

An addition table supports third graders as they learn strategies to improve their math fluency. When finding sums greater than ten, students are taught how to first make a ten and then add on the rest. A similar method is also...

Add visual representation to teaching place value with a magnitude model. Using adding machine tape, pupils build a linear place value strip from 1 to 100.

Pupils practice rounding numbers to the nearest ten and hundred. They solve rounding numbers word problems, and add and subtract rounded numbers. This nice, neat handout fully serves its purpose and can help meet CCSS.Math.Content.3.NBT.1.

Create a class of mathematics master. They practice addition to ten until they have mastered the skill. They use their hands to add numbers and eventually find the missing addend to make a sum of 10. They also subtract a single digit...

Build on your learners' confidence in quick addition as they discover strategies to add tens to two-digit numbers. After reviewing counting by 10's, they discuss tactics to add multiples of 10 to other numbers. They visualize how to...

Learners are introduced to the concept of imaginary unit and complex numbers. They are taught how to add and subtract complex numbers. Students define a complex number. They comprehend at least two applications of complex numbers....

Young mathematicians spin their way to a deeper number sense with this fun, collaborative activity. Using two spinners, one with the numbers 0-9 and the other with the decades 00-90, pairs of students take turns building and comparing...

Students explore adding 2-digit numbers. In this math activity, students identify 2-digit numbers and use base ten blocks to practice adding. Students use addition to break a code.

Add some randomization into simulations. The 11th installment in a series of 25 presents two new methods to use in simulations--colored disks, and random numbers. Pupils use random numbers to run simulations where the probabilities make...

Learning how numbers are put together as parts and wholes is a big step in building the foundational number sense of young mathematicians. Here, children are given a number less than 10 and are asked to find as many pairs of numbers as...

Explore place value and regrouping with your class. They develop awareness of several ancient number systems and how they differ from the base ten system commonly used today. They play "Chip Trading" with partners to practice addition...

Fifth and sixth graders compare decimals to the place-value structure in the base-ten number system. They represent fractions as parts of unit wholes, as parts of a set, as locations on a number line, and as divisions of whole numbers....

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...

Young learners listen to a read aloud of Gail Gibbons book, Apples and the story A Red House With No Windows and No Doors. They compare characteristics of a number of kinds of apples, graph them and create a apple print picture. Learners...

Get learners to analyze two-digit numbers based on place value, and use manipulatives to add and subtract both 1 and 10. A place value chart is available, and you can project it during guided practice. Through visualizing...

Students simulate a Mayan market place, and "purchase" items. They keep a record of their purchases and total number of beans left in their account. Students then convert the Mayan base system into the base ten system. This lesson plan...

New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

Count and compare numbers and fractions using "greater than" and "less than." Learners count on by 2s and 10s and represent the end number with base ten blocks, counters, and cups. They use circle stickers to illustrate fractions and...

For this algebra worksheet, students add, subtract and multiply using complex numbers. They apply the correct property of i as they solve. There are ten questions with an answer key.
