Which decimal number is illustrated practice

A hundred-square grid turns a decimal into something you can point at. Each column is one tenth, each small square is one hundredth, and the shaded part is the number. That is why 0.8 and 0.80 cover exactly the same area, even though one looks longer.

The page builds the habit in two moves: count the full columns, then the leftover squares, and only then choose between options like 0.70, 0.76 and 0.66. Writing the result in words adds a second check, because the word name has to match the count. That is tenths and hundredths on a grid at work.

The skill sits in 4.NF.C.6, decimal notation for fractions with denominators 10 or 100. In sixth grade it is a quick warm-up before longer decimals.

Start with the orange grid. Ask, "How many full columns can you count?" Seven full columns make 0.70, and that choice is printed right there for anyone who stops early. The six extra squares in the next column are what move it on.

The pale green grid trips kids the other way. Its eight columns look like a lot, and 0.08 sits beside 0.8. Ask, "Is that eight squares or eight columns?"

On the yellow grid, let your child count the white squares instead of the colored ones. One white square means the grid is one hundredth short of a whole.

The instruction says "in word" where it means in words: your child writes the full name, such as fifty-three hundredths.

Spill a handful of change on the table and count it in cents. Seventy-six cents is 76 hundredths of a dollar, so ask your child to write it as 0.76 and read it aloud. A grocery receipt works the same way, one cent at a time.

A Battleship board is also a 10 by 10 grid. After a game, count the squares your child hit and name them as a decimal of the ocean: 17 hits are 0.17 of the board.

When the four grids are done, say what your child did: "You counted columns first, then squares." The next sheet in the series turns the habit around, from digits to long word names.
