Show young mathematicians that they are fully capable of mentally adding two-digit numbers. They start by solving 12 two-addend problems (all with two-digit numbers and aligned horizontally). There is no room to show work. Consider...

Students practice skip counting strategies, estimation, and higher number addition. They estimate the number of seeds in bell pepper, and count seeds in groups of tens and ones after the teacher removes seeds from the pepper.

Here is an engaging presentation that challenges your mathematicians to use the techniques of partitioning and halving in order to double or half numbers. After each technique is explained, learners are given a series of numbers to try...

You can't build a fire with these logs! Filled with hands-on investigations, a complete logarithmic unit offers both instruction and practice. Learners first build an understanding of the new function, then explore properties before...

Learners practice estimating by handling items in groups of ten. They visualize how much space 100 items, such as pennies, peas, or beans, will take up after holding 10 of them. Students measure the difference in volume between 10...

In this building numbers worksheet, students fill in the table using the base ten and square unit blocks to build numbers. Students write the numbers into the tens and ones block.

In this quantities and numbers activity, students learn how to visualize quantities in the hundreds, tens and ones with number blocks and dots. They also practice writing numbers in word format and number format. There are 20 problems to...

Groups explore sets of 10 items in two varieties (i.e. 3 white buttons and 7 black ones, or 5 bears and 5 bunnies). They brainstorm about their objects, write math sentences to represent what they have, and report their discoveries...

Learners explore place value. This incredibly thorough and valuable mathematics lesson, has learners make a number wheel to assist in the completion of a Place Value worksheet. Students use manipulatives and a place value mat to further...

In this questing numbers learning exercise, students use algebra equations to discover how the teacher correctly chooses the students' numbers each and every-time.  A pencil, key, stamp, yarn, and overhead are needed for this activity.

Students explore the concept of place value with a hand-made odometer. In this math activity, students construct a cardboard odometer with movable paper strips to show increases in mileage to the hundredths place. Students solve story...

For this place value worksheet, 2nd graders identify the correct number for the tens and ones given. There are eight problems for students to complete.

Learners practice counting by 10s, 5s, and 1s in order to prepare for counting and adding the values of coins.

In this partitioning numbers worksheet, students partition the given numbers into their hundreds, tens and units. Students write the numbers on the blanks.

In this place values worksheet, students partition the numbers into their thousands, hundreds, tens, and units. Students enhance their understanding of place values.

Tackle the concept of decimals and place value. Each of the four slides in this compact presentation displays a different aspect of place value as it relates to decimal numbers to the thousandths. Very simple, very clear, and comprehensive.

Who knew two hands could solve so many problems? Kids learn the 9's times tables trick with their fingers, then work through a series of 9's related math problems intended on building strong number sense and pattern recognition. Great...

Students recall word problems that involve place value along with conversion of decimals to fractions. Included are hundreds, tens, units, tenths, hundredths and thousandths. They independently work on a variety of equations converting...

Calling all cars! It's time to solve some division problems! A chart of special police units and the number of officers in each provides the data for six word problems. Young recruits use their division skills to solve them. Note that...
