One Change Leads to Another

Write + 1000, +100, +10, +1, -1000, -100, -10, -1, +.01, -.001, etc, on notecards. Mix up the cards and add to a large hat or box (or in a pile on the floor if you do not have those items available). Have a student select a card and add or subtract place value blocks […]

Expanded Form

Have a student create a number and jump it out on the mat. After reading the number, have them write each numeral’s value on an index card and place it above each numeral. For example, after reading the number 24.398 students would write 20 on a card and place it above the 2, 4 and […]

Rounding

Have a student create a number on the mat. Then, have them round the numbers to all of the different place values. Use 0 cards for any place after the place value they are rounding to. Grade 3: Round to 10s and 100s Grade 4: Round to nearest tenth or hundredth. Grade 5: Round to […]

Multiplying

Have a student create a number on the mat. Then, have them multiply it by 100, 10, .10 or .01. Which way do the digits shift? Have them move the number cards to reflect the new number.

Comparing Numbers

Make a number on the mat with numerals, e.g. 230.46 and make a number similar to it above it in line with place value, such as 230.046. Ask the students to compare which number is bigger. Do with several numbers.

The Place Value Walk

Stand on the mat on the ones column. Say, “ones.” Step to the tens, say, “tens.” Then to the hundreds, say, “hundreds,” and to the thousands, say, “thousands.” Continue to “millions.”

The Place Value Walk – Backwards

Stand on the mat on the millions column. Say, “millions.” Step to the hundred thousands, say, “hundred thousands.” Then to the ten thousands, say, “ten thousands,” and to the thousands, say, “thousands.” Continue to “ones.”

Hopping Place Values

Have students create a number by placing the numeral cards in the boxes at the top of the floor mat. Example: Create the number 2,345,678. Start at the ones column. Jump on the 8 and say, “8 ones.” Jump on the 7 and say “7 tens.” Jump on the 6 and say, “6 hundreds.” Jump […]
