Kindergarten AB Pattern Worksheet: Two Colors Take Turns, Circle the Next One

Clap, pat, clap, pat: most five-year-olds can keep that rhythm going long before they can explain it. This kindergarten AB pattern worksheet puts the same idea on paper with color. Four rows show one shape in two colors taking turns: red and pink hearts, yellow and green stars, blue and orange pentagons, then brown and pale green triangles. At the end of each row, your child circles the color that comes next. Each row stops at a different place, and that is the real puzzle. The PDF ends with an answer key page.

Why color is the right place to start

An AB pattern is the simplest rule there is: one thing, then another, again and again. Spotting it is early algebra in plain clothes, because the child finds a rule and then uses it to predict.

Here the shape never changes inside a row, so color is the only clue. That keeps pattern recognition clean: no distractions, just two repeating colors.

However, the rows are not the same length. The hearts stop after six, the stars after seven, and the last two rows after five. So the answer is not always the first color of the row. Your child has to look at the last shape, not the first one.

At the table: say the pattern out loud

Ask your child to read each row with their voice: "Red, pink, red, pink." Tap each heart while saying its color. When the voice reaches the end of the row, the next word often comes out by itself.

The stars are the row to watch. Because that row is longer, a child may assume it ends like the hearts and pick the same color as before. Instead of correcting, ask, "What color is the last star?" Then ask what comes after it.

On some printers, the pale green triangles can look almost gray. Name the two colors together before starting.

This habit of predicting the next step from the last item is the whole skill. Look at the end first.

Socks, beads and Pattern Fish

Patterns are everywhere once you look for them. While you fold the laundry, lay socks in a line, one dark and one light, and ask your child to add the next one. At snack time, build an AB pattern with two kinds of crackers.

Also, read Pattern Fish by Trudy Harris. Its sea creatures wear stripes and spots that repeat, and the text has a rhythm children like to chant. Stop on a page and ask, "What comes next?"

Finally, check the page with the answer key. Praise the looking, not the speed: "You checked the last shape before you chose. That is careful thinking."
