Free 2nd Grade Revision Exercise. Lesson Plan (Math)

Topic: revision exercise on odd, even, ordinal, cardinal numbers, halving, doubling, addition, subtraction

Objectives & Outcomes

• To revise and reinforce the concept of odd and even numbers, ordinal and cardinal numbers, halving and doubling, addition and subtraction.

Materials

• Whiteboard and markers
• Handouts with exercises on odd, even, ordinal, cardinal numbers, halving, doubling, addition, subtraction

Warm-up

• Ask the children to pronounce and identify numbers from 1 to 20. Write the numbers on the board and have the children point to the number if it is even or odd.
• Ask the children to recite the properties of even numbers (can be divided by 2 without remainder, even number of elements in a set) and odd numbers (can be divided by 2 without remainder, odd number of elements in a set).

Direct Instruction

• Introduce the concept of ordinal numbers and explain that they are used to show the order of things.
• Show the children how to write the ordinal numbers from 1 to 20.
• Introduce the concept of cardinal numbers and explain that they are used to quantify the amount of things.
• Show the children how to write the cardinal numbers from 1 to 20.
• Review the halving and doubling procedures for numbers up to 100.
• Demonstrate how to add and subtract numbers up to 100.

Guided Practice

• Have the children work in pairs and provide them with a set of cards with numbers on them.
• Have them place the cards in order from 1 to 20.
• Then have them use the chart to write the ordinal and cardinal numbers.
• Next, have them use the math manipulatives to add and subtract numbers up to 100.

Independent Practice

• Have the children work in groups and create a game using the math manipulatives to add and subtract numbers up to 100.
• Have them present their game to the class and explain how to play it.

Closure:

• Review the concepts learned during the lesson, including odd and even numbers, cardinal and ordinal numbers, halving and doubling, addition and subtraction.
• Ask the children to share something they learned during the lesson.

Assessment:

• Observe the children during the mini-LESSon and discussion, and take notes of their understanding of the concepts.
• Collect the children's written work and review it to assess their understanding of the concepts taught during the lesson.
• Ask the children a few questions to assess their understanding of the concepts taught during the lesson, e.g. "What is an odd number?" "What is an even number?".
• Ask the children to reflect on what they learned during the lesson and share their thoughts with the class.
