Free Unit 2 (Representing Numbers To 120) Lesson Plan for 1st Grade Students

Topic: Representing numbers to 120 in standard and expanded forms

Objectives & Outcomes

• Students will be able to represent numbers to 120 in standard and expanded forms.
• Students will be able to use concrete objects (counters and double ten frames, straws (bundled), linking cubes, base-ten blocks, place value disks), pictorial models (double ten frames, base ten representations on a place value chart) and numerical representations (expanded, written and standard form) to represent numbers to 120.

Materials:

• Concrete objects (counters and double ten frames, straws (bundled), linking cubes, base-ten blocks, place value disks)
• Pictorial models (double ten frames, base ten representations on a place value chart)
• Numerical representations (expanded, written and standard form)

Warm-up

• Review the concept of place value, showing how the value of a digit in a number changes based on its position (e.g. in the number 34, the 3 is in the tens place and the 4 is in the ones place). Have students give examples of numbers with different place values.

Direct Instruction

• Introduce the concept of expanded form, explaining that it is a way of writing numbers that shows all of the digits in the number, including the ones place (tens place if there are more than one digit in the ones place).
• Show examples of numbers in expanded form, using concrete objects or place value disks.
• Introduce the concept of standard form, explaining that it is a way of writing numbers that shows the ones place first, followed by the tens place, then the hundreds place, etc.
• Show examples of numbers in standard form, using concrete objects or place value disks.

Guided Practice

• Have students work in pairs or small groups, providing each group with a set of counters or base ten blocks.
• Have students use the counters or base ten blocks to represent a number in expanded form, then have them write the number in standard form.
• Have students share their solutions with the class, discussing any challenges or questions they had along the way.

Independent Practice

• For independent practice, have students work on a project-based activity where they have to represent a number to 120 in both expanded and standard forms, and create a visual representation of their solution (e.g. using double ten frames, base ten blocks or place value cards).
• Provide students with a variety of options for how they can represent their solutions, and encourage them to be creative and use their own ideas.

Closure

• Review the objectives for the lesson and ask students to share their solutions to the project-based activity.
• Ask students to share any challenges they faced and how they were able to overcome them.

Assessment

• Observe students during independent practice to assess their understanding of the material.
• Collect and review the projects completed for evidence of student understanding.
