Give students a handle on place value and number concepts!

Get a handle on place value and number concepts! Set of 5 double-sided write & wipe boards features one side for large numbers up to the millions; the reverse for small decimals to the thousandths place.

Raise the stakes on your teaching of number sense and place value! Versatile boards feature color-coded spaces to write in decimals on one side and numbers on the reverse. The blank, color-coded place-value squares match
the color sequence of Learning Resources® Place Value Rods, inviting students to engage in manipulative-based learning individually or in small groups. What’s the holdup? Get your hands on these dazzling, double-sided displays and start creating numbers today!

Note: Write on the boards with a dry- or wet-erase marker. Do not saturate the boards with water or cleaning solution. This could warp the boards.

Fun Classroom Uses:
Mystery Digits—Divide the class into several small groups. Give each small group one board. Think of a mystery number for the groups to solve on their boards. For each digit of the mystery number, call out or write a “clue” on the classroom whiteboard that describes where students should place the digit (for example, put a 4 in the tens place, put an 8 in the hundreds place,
and so on). When you finish calling out clues, ask: “What number did we make?” Have a volunteer from each group hold the board up to show the answer and read the number properly! The numbers they have created are now in standard form—the way we typically see numbers in everyday life.

Expanded Form to Standard Form—Expanded form shows the sum of the values of each digit in a number. For example, the number 342 in expanded form is 300 + 40 + 2. Show students the expanded form of this number on the board. Then, have them write the corresponding number on their answer boards. Encourage students to discover that 300 in this number is represented by a 3 in the hundreds place, and so on. Continue to write numbers in expanded form on the board, and have students show the same numbers in standard form on their Place Value Answer Boards. Reading the numbers in standard form aloud will reinforce their understanding.

Show expanded form with decimals also, such as in the number 2.56, whose expanded form is written as 2 + .5 + .06. Write this number in expanded form on the board, and have students use their Place Value Answer Boards to write the number in standard form. Students should demonstrate their understanding by writing a 2 in the ones place, a 5 in the tenths place, and so on. Ask students to read their numbers aloud so you can assess their understanding.

Word Form to Standard Form—Display on the board whole or decimal numbers written out in word form, such as “twelve and fifty-eight hundredths,” or “three hundred forty-two thousand six hundred twenty-one.” Have students write these numbers in standard form on their boards and hold them up to share answers.

Teaching tip: If students have trouble writing longer numbers in standard form, encourage them to break the word form into “chunks” to show the placement of a comma or decimal. For decimals in word form, as in example 2 and one tenth (2.1), have
students break the word form into two chunks: before and after the word and, which represents the decimal place. By circling or underlining the word and in word form, students are able to see where the decimal appears in the standard form.

Rounding Numbers—Have students write a particular number on their answer boards; for example 4,356. Tell them to round the number to different place values, such as tens, hundreds, and thousands. Notice how the answers change depending on the value being rounded to. You can also do the same thing with decimals on the reverse side.

A Contest of Numbers—Hold team competitions in the classroom. Split the classroom into two teams. Pass out one board to the first person on each team. Call out a number. The first person (or team) to write the number correctly on a board and hold it up wins! Also, try using the reverse sides of the boards for a daring decimal race!
