Lesson Plan: 1st Grade Addition and counting to 20 Objective: Students will be able to solve simple addition problems and addition word problems using manipulatives, visual representations, and number sentences Procedure: Warm-up (5 minutes): Review counting: Quickly review counting from 1 to 20, emphasizing the sequence. Quick addition facts: Flash a few simple addition problems (e.g., 2 + 1, 3 + 2) and have students call out the answers. Introduction (10 minutes): Manipulative activity: Place 3 counters on the table, then add 2 more. Ask students how many counters are there in total (5). Repeat with different combinations of counters, encouraging students to count and explain their thinking. Visual representation: Draw a picture on the board showing 2 apples and then add 1 more apple. Ask students to write the number sentence (2 + 1 = 3) to represent the picture. Introduce "addition" vocabulary: Explain that "adding" means putting together, and the "+" sign represents adding. Guided Practice (15 minutes): Addition sentences: Write a few addition sentences on the board (e.g., 4 + 1 = ?, 2 + 3 = ?) and have students solve them using counters or by drawing pictures. Word problems with visuals: Show picture cards with simple addition scenarios (e.g., "There are 2 birds on a branch, 1 more bird flies to join them. How many birds are there now?"). Guide students to write the number sentence and solve the problem Review key points: Ask Dalton to share a few addition problems they solved on the worksheet and explain how they got the answer. Differentiation: For struggling students: Provide more hands-on activities with manipulatives, use simpler addition problems, and offer extra support with reading word problems. For advanced students: Introduce larger numbers, challenge students to create their own word problems, or have them practice writing addition facts with the commutative property (e.g., 2 + 3 = 3 + 2). Addition Worksheets: Basic Addition: 2 + 1 = 3 + 2 = 1 + 4 = 5 + 0 = Word Problems: "There are 3 dogs playing in the park. 2 more dogs come to join them. How many dogs are playing now?" "Lily has 4 cookies. Her friend gives her 1 more cookie. How many cookies does Lily have now?" Note: Remember to adjust the difficulty level of the worksheets based on your students' abilities and progress. / Lesson Plan

Objective

By the end of this lesson, Dalton will be able to solve simple addition problems and word problems using counters and drawings. He will understand how to represent addition with number sentences and will have fun while learning!

Materials and Prep

  • Counters (like small toys, blocks, or any small items)
  • Paper and crayons for drawing
  • Whiteboard and markers
  • Picture cards for word problems (can be drawn or printed)
  • Worksheets with addition problems and word problems

Activities

  • Counting Warm-Up: Start by counting together from 1 to 20. This will help Dalton get ready for the addition activities!

  • Counter Addition: Use counters to demonstrate addition. For example, place 3 counters on the table, then add 2 more. Ask Dalton to count them all and tell you how many there are.

  • Draw and Add: Draw pictures of apples on the board. For example, draw 2 apples and then add 1 more. Dalton can write the addition sentence (2 + 1 = 3) to show what he did!

  • Word Problems: Use picture cards to create simple word problems. For instance, show a picture of birds and ask, "If there are 2 birds and 1 more comes, how many are there now?"

  • Worksheet Fun: Dalton will complete worksheets with addition problems and word problems. He can use counters or drawings to help him solve them!

Talking Points

  • "When we add, we are putting things together. Can you say 'adding' with me?"
  • "The '+' sign means we are adding! Let's look at our counters and see how many we have when we add!"
  • "Can you count the total number of counters? How did you figure that out?"
  • "Let’s draw a picture of our problem! What does 2 apples plus 1 apple look like?"
  • "When you read a word problem, what do you think we need to find out? How many do we have in the end?"
  • "Great job! Remember, it’s okay to use your fingers or counters to help you. Learning is fun!"
