๐ Visual Strategies for Teaching Numbers 11-19 with Ten Frames
This guide provides educators with visual strategies for teaching numbers 11-19 using ten frames. Ten frames are a powerful visual tool that helps students develop number sense and understand place value. These strategies cater to different learning styles and promote a deeper understanding of numbers beyond rote memorization.
๐ฏ Objectives
- ๐ฏ Students will be able to represent numbers 11-19 using ten frames.
- ๐ข Students will be able to decompose numbers 11-19 into ten and some ones.
- ๐ฃ๏ธ Students will be able to verbally express the composition of numbers 11-19 (e.g., 15 is ten and five).
- ๐ค Students will be able to compare numbers 11-19 using ten frames.
Materials Needed
- ๐ผ๏ธ Ten frame templates (printed or digital)
- ๐ด Two-colored counters or manipulatives
- โ๏ธ Whiteboard or chart paper
- ๐ Markers or pens
- ๐งฎ Number cards (11-19)
Warm-up Activity (5 minutes)
- ๐ Review numbers 1-10 using ten frames. Display a ten frame and ask students to fill it with counters to represent a number from 1-10.
- ๐ฃ๏ธ Have students verbally state the number represented in the ten frame.
Main Instruction
Introducing Numbers 11-19
- ๐ Introduce the concept of numbers 11-19 as "ten and some more."
- ๐ผ๏ธ Use ten frames to visually represent this concept. For example, to represent 11, fill one ten frame completely and place one counter in the second ten frame.
- ๐ฃ๏ธ Verbally state, "11 is ten and one more."
Guided Practice
- ๐ค Work through several examples together as a class.
- ๐งฎ Show a number card (e.g., 14) and ask students to represent it using ten frames.
- ๐ฃ๏ธ Encourage students to explain their reasoning: "I filled one ten frame completely, and then I put four counters in the second ten frame. So, 14 is ten and four more."
Independent Practice
- ๐งโ๐ Provide students with individual ten frame templates and counters.
- ๐ Give them number cards (11-19) and ask them to represent each number using ten frames.
- ๐ถ Circulate the classroom, providing support and guidance as needed.
Decomposing Numbers
- โ Emphasize the decomposition of numbers 11-19 into ten and some ones.
- ๐ผ๏ธ Use ten frames to illustrate this concept. For example, show 16 represented in ten frames (one full ten frame and six counters in the second ten frame).
- ๐ฃ๏ธ Ask students, "How many tens are there? How many ones are there?"
- โ๏ธ Write the equation on the board: $16 = 10 + 6$
Comparing Numbers
- โ๏ธ Use ten frames to compare numbers 11-19.
- ๐ผ๏ธ Represent two numbers (e.g., 12 and 15) using ten frames.
- ๐ Ask students to compare the two representations. Which number has more ones? Which number is greater?
- ๐ฃ๏ธ Encourage students to use comparative language: "15 is greater than 12 because it has more ones."
Assessment
- ๐ Provide students with a worksheet containing numbers 11-19.
- ๐ผ๏ธ Ask them to represent each number using ten frames by drawing counters in the frames.
- โ
Evaluate their understanding of representing and decomposing numbers 11-19 using ten frames.
