Welcome to a tiny Math Dictionary that has words that start with X .
There aren't many words that begin with the letter X, much less Math words; but the list of X words below is helpful especially when you're trying to think of x words for a game.
Remember to include Math vocabulary any time you can. I really think that it is important to simply repeat the definitions three times each. Making a quick review of a definition helps students remember it in the future. Wouldn't it be great if all students could remember which is the x-axis?
Use the links in the alphabetical chart to go to other sections of our dictionary.
X-Axis - the horizontal axis in the plane.
X-Intercept - the point at which a line crosses the x-axis.
X-Pentomino - a pentomino in the shape of the letter X.
X - Roman numeral for 10. See Roman Numeral worksheets here.
Hint: Roman numerals often count as words on crossword puzzles. XX, XXX, XXI, etc.
Okay. Here are some more words that start with X that you can use. Tell the little ones to count the bars on a Xylophone, count how many ribs are in an Xray picture, or count the ornaments on a Xmas tree.
