Decimal Place Value Charts / Mats / Sheets – 7 Variations

There are multiple variations of the decimal charts included in this product, all intended to be printed in landscape orientation on regular printer

paper or cardstock (8 1/2 x 11”). *Special note: Some table borders may not display in .PDF format on your monitor. However, they do print properly!

Materials Included:

• 7 decimal place value charts, with whole number places from units to thousands, and decimal places from tenths to millionths

o Chart 1: Blank columns, in color (no text or numbers)

o Chart 2: Place value names using “units”

o Chart 3: Place value names using “ones”

o Chart 4: Place value numeric values

o Chart 5: Place value fractional values

o Chart 6: Place value numeric values and place value names using “units” (can be used as a chart, if desired, or as an answer key for place value name labels)

o Chart 7: Place value numeric values and place value names using “ones” (can be used as a chart, if desired, or as an answer key for place value name labels)

• Labels for columns and column names

o Place value names, from thousands to millionths

o Numeric values from thousands to millionths, in both decimal and fraction formats

• 5 lesson ideas for using these materials

The decimal place value charts can be used to introduce the decimal system in relation to whole numbers. They can also be used with Montessori

decimal cubes or numeral cards to learn how to say decimal numbers, and add or subtract decimals. Additionally, you can use the labels in various

lessons to introduce the names and values of the places. Children can use these materials independently or with another child as a center activity

or on the math shelf. The charts could be printed and written on as practice sheets for writing decimal numbers, and adding and subtracting

decimals, or laminated for reusable practice sheets.

The colors of the place values correspond to Montessori place value colors. The decimal places are lighter shades of the whole number place value colors to represent that place value being broken down into more and more pieces. For example, the tens place is royal blue, the tenths place is

light blue (tens being broken down into smaller pieces) and the ten-thousandths place is even lighter blue, (indicating even smaller pieces).

In the classroom

Teaching tips & learning objectives

Learning objectives

Identify and name place values from thousands through millionths on a decimal place value chart.
Represent a decimal quantity using counters or beads placed in the correct place-value column.
Read a decimal number aloud correctly, naming the rightmost occupied place value (e.g., "thirty-six hundredths").
Add and subtract decimal numbers using a place-value mat as a visual/manipulative aid.

Teaching tips

Print and laminate Chart 1 with the labels as reusable, write-on/wipe-off practice mats.
Introduce the fraction-to-decimal relationship first using Chart 5 before moving to purely numeric Chart 4.
Use Charts 6 and 7 as a self-checking answer key once students have practiced placing name and value labels on the blank chart.
Have two students take turns placing beads and naming the resulting decimal quantity for peer practice.

Skills covered

Decimal place-value identification — students name columns from thousands to millionths on a color-coded chart.
Decimal-fraction equivalence — students match decimal place values (e.g., .1, .01) to their common-fraction equivalents (1/10, 1/100).
Decimal quantity building — students place counters in place-value columns and verbally name the resulting quantity.
Decimal addition and subtraction — students solve and read aloud decimal addition/subtraction problems written directly on a place-value mat.

Good to know

Questions teachers ask about this resource

How do the seven chart variations relate to each other for a teacher choosing which to print?

They form a deliberate sequence from unlabeled (Chart 1, for open placement practice) to fully labeled (Charts 6-7, which pair numeric values with place-value names), with Charts 2-5 adding just names or just values in between so a teacher can match the chart to the lesson stage.
