Learning Objectives

  • Students will understand how to write numbers from 21 to 99 in words.
  • Students will correctly format numbers with both tens and ones, using hyphens.
  • Students will accurately convert numbers written in digits into their word forms.

Introduction

Introduce the concept of writing numbers in words by showing a list of numbers from 21 to 99 on the whiteboard. Explain the structure of these numbers, emphasizing the use of tens and ones. Present the example problem: "How do you write the number 40 using words?" Show the process of writing the number in words, breaking it down into tens and ones.

Explicit Instruction/Teacher modeling

Explain that each number can be written in words and numerals. Show examples on the board, such as:

  • 5 = Five
  • 12 = Twelve
  • 19 = Nineteen

Break down the components of numbers higher than 20, showing how the tens and units are combined:

  • 34 = Thirty-four
  • 58 = Fifty-eight

Use number cards to reinforce the concept, displaying both the numeral and word form.

Guided Practice

Distribute the first worksheet from the TeachTastic Worksheet Pack for Writing Numbers in Words. Work through the first few problems as a class. For instance, convert "84" into words by writing "eighty-four." Encourage students to follow along and use their printed number charts.

Independent Practice

Students will complete additional problems from the TeachTastic Worksheet Pack independently. Tasks will include converting numbers written in digits from 21 to 99 into their word forms.

Differentiation

Support

  • Use Visual Aids: Display charts showing numbers in both digit and word forms for easy reference.
  • Use Manipulatives: Provide students with physical number cards to manipulate and arrange in word form.

Extension

  • Number Puzzles: Provide challenging puzzles where students write complex numbers in words, including those with hundreds.
  • Real-Life Application: Ask students to write out numbers they encounter in daily life, such as prices or quantities, in word form.

Assessment

Evaluate students' understanding through the exit ticket and the completed independent practice worksheets. Check for accuracy in writing numbers in words and proper use of hyphens for numbers with both tens and ones.

Review and closing

Summarize the key points of the lesson, including how to write numbers in words and the importance of understanding numerical representation. Address common misconceptions, such as incorrect use of hyphens or confusing the order of tens and ones. Allow students to ask questions and share their observations about writing numbers in words.

Misconceptions

  1. Incorrect use of hyphens: Reinforce the rule of using hyphens between the tens and ones parts.
  2. Confusing the order of tens and ones: Ensure students understand the correct order when writing numbers in words.
