C.2 Count stars 0-20 with ten frames

Loading questions...

Understanding Ten Frames

A ten frame is a simple tool that helps children visualize numbers up to 10. It is a rectangle with two rows of five boxes where stars or objects are placed to represent numbers.

Ten Frame Activities:
  • Fill a ten frame with 5 stars and count aloud.
  • Ask: “If we add 2 more stars, how many are there now?”
  • Display an empty ten frame and explain it shows zero.
Teaching Tip

Encourage children to see how numbers build up in a ten frame from left to right. This helps them understand how numbers grow.

Counting Stars on Ten Frames

Counting stars placed on a ten frame helps children understand that numbers represent quantities. Each star is counted once to find the total number.

Counting Practice:
  • Show a ten frame with 8 stars and count them aloud together.
  • Ask children to count 11 stars using a filled ten frame and an additional frame with 1 star.
  • Say: “There are 15 stars in total” after counting them all.
Instructional Reminder

Have children point to each star as they count. The last number they say is the total number of stars.

Recognizing Numbers with Ten Frames

Matching the number of stars on a ten frame to a written number helps children connect visual quantities with numerals they can read.

Matching Examples:
  • Show a card with 10 and ask children to find a full ten frame.
  • Display 14 stars using one full frame and four more on the next frame.
  • Present the number 0 and ask: “Which ten frame is empty?”
Helpful Tip

Use number cards alongside ten frames to reinforce the connection between numerals and counted stars.

Counting Stars Beyond Ten

Counting beyond ten introduces children to teen numbers. Using multiple ten frames helps them see how numbers are built from groups of ten plus extra ones.

Teen Number Practice:
  • Fill one ten frame and add 3 more stars → “How many stars now?” (Answer: 13)
  • Show 17 stars by filling one ten frame and adding 7 on another.
  • Ask: “How many more stars are needed to reach 20?”
Visual Reminder

Explain that numbers after 10 are made of a full ten frame plus some more stars on the next frame. This helps children understand numbers like 11-20.

Subitizing Stars on Ten Frames

Subitizing is the ability to instantly recognize how many stars are on a ten frame without counting them one by one. This builds quick number recognition up to 10.

Subitizing Examples:
  • Flash a ten frame with 4 stars and ask: “How many stars?”
  • Show 7 stars and let children say the number instantly.
  • Quickly display a full ten frame to build fluency with recognizing 10.
Practice Tip

Use quick visual displays of stars to help children build subitizing skills. Start with small groups and gradually move to full ten frames.

Comparing Numbers on Ten Frames

Comparing two ten frames helps children understand the concepts of more, less, and equal. This develops early reasoning about numbers.

Comparison Activities:
  • Show one ten frame with 6 stars and another with 9 → “Which has more?”
  • Display two ten frames with 8 stars each → “Are they equal?”
  • Present a frame with 4 stars next to one with 7 → “Which has fewer?”
Visual Strategy

Place ten frames side by side so children can clearly see which group of stars is bigger, smaller, or the same.

Building Number Fluency with Ten Frames

Frequent practice with ten frames helps children become fluent in counting, recognizing, and comparing numbers up to 20. Consistent visual and hands-on activities strengthen number sense.

Fluency Activities:
  • Use flashcards showing ten frames with different star counts.
  • Practice filling empty ten frames to match a given number.
  • Challenge children to build numbers like 12 or 18 using multiple ten frames.
Instructional Focus

Encourage children to explain their thinking as they count and build numbers. This deepens their understanding and prepares them for future math skills.
