Free Unit 1- Representing Whole Numbers To 120 Lesson Plan for 1st Grade Students

Topic: Representing Numbers to 120

Objectives & Outcomes

• Students will be able to recognize numbers to 50 in more than one way (double ten frames, linking cubes and base ten tens and ones).
• Students will be able to compose and decompose numbers in more than one way (double ten frames, linking cubes and base ten tens and ones).
• Students will be able to instantly recognize numbers from patterns (example patterns on ten frames, snap cubes, dominos, dots on a number cube – 6 black dots and 2 two white dots…)

Materials

• Double ten frames
• Linking cubes
• Base ten tens and ones
• Snap cubes
• Dominos
• Dots on a number cube
• Place value charts
• Number lines

Warm-up

• Review counting with units of ten (1-10).
• Review counting with units of one (1-10).
• Ask students to count to 50 by ones, then by tens.
• Review the pattern for counting by ones (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
• Ask students to count to 50 by tens, then by ones.
• Review the pattern for counting by tens (10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, 500)
• Review the fundamental of the base-ten and place value systems through the use of double ten frames; by thinking in terms of “tens” and “ones” students can more efficiently count with unitizing and counting on (instead of one-to-one correspondence) for the understanding of whole numbers to 120.

Direct Instruction

• Introduce the concept of unitizing by demonstrating how to use linking cubes to represent a number up to 50.
• Introduce the concept of counting by tens to help students understand the place value system.
• Introduce the concept of counting by ones to help students understand the place value system.
• Introduce the concept of decomposing by demonstrating how to use linking cubes to break apart a number up to 120 into its tens and ones.
• Introduce the concept of composing by demonstrating how to use linking cubes to compose a number up to 120 by uniting its tens and ones.
• Introduce the concept of composing and decomposing by demonstrating how to use linking cubes to compose and decompose a number up to 120 in more than one way.

Guided Practice

• Have students work in pairs and follow along with the teacher as he/she demonstrates how to compose and decompose numbers up to 120 in more than one way, using linking cubes.
• Give each pair of students their own set of linking cubes and have them practice composing and decomposing numbers up to 120 in more than one way.
• Go around the room and assist students as needed.

Independent Practice

• Have students work on a project-based activity in which they compose and decompose numbers up to 120 in more than one way, using linking cubes.
• Students should use their double ten frames and base ten tens and ones to assist them in their project.
• Provide support and guidance as needed.

Closure

• Review the objectives and key concepts of the lesson.
• Ask students to share their favorite parts of the lesson and why they found them to be engaging and/or challenging.
• Ask students to share one thing they learned during the lesson and how they can apply it at home or in other areas of their lives.#lesson-planning-resources#
• Go to Google Drive and create a new folder called Unit1-120. Make it a shared folder so that anyone with access can add files to it.
• Using the Project-Based Learning template, create a new file and upload the files for the project, including the blueprint, rubric and any additional materials.
• Go to the Classroom and create a new activity called “Independent Practice”.
• Copy the “Understanding Number Patterns to 120” activity plan and edit it to refer to the new shared folder and project title.
• Assign the activity to students and have them work on their project.

Observation

• During guided practice, observe student’s to make sure they are able to count to 120 using the base-ten system and place value.
• During independent practice, observe students to make sure they are able to create a project that demonstrates their understanding of numbers patterns to 120. You can also use this time to assess student’s understanding of the material.
