Key Concepts

  • Addition within 100
  • Solving word problems
  • Place value (tens and ones)

Learning Objectives

  • Students will be able to solve addition word problems with numbers up to 100.
  • Students will be able to add two-digit numbers using place value understanding.
  • Students will be able to explain their reasoning when solving addition problems.

Educator Instructions

  • Introduction (5 mins)
    Start by asking students if they have ever played a game with spinning wheels. Discuss how numbers can be used in games. Introduce the idea that we will be solving a math problem about a spinning wheel game.
  • Video Viewing (5 mins)
    Play the Khan Academy video 'More word problems | Addition and subtraction within 100 | Early Math' (https://www.youtube.com/watch?v=jDIj0CUjGvM). Encourage students to pay attention to how the problem is solved step-by-step.
  • Guided Practice (10 mins)
    Work through the example problem from the video together as a class. Write down the numbers Emeka and Tom got (17 and 15 more than 17). Ask students to explain how they would find Tom's number. Guide them through the process of adding 17 + 15, emphasizing the place value concept of adding ones and then tens. Reinforce carrying over when the sum of the ones is greater than 9.
  • Independent Practice (10 mins)
    Present students with similar word problems. For example: 'Sarah has 23 stickers. Michael has 12 more stickers than Sarah. How many stickers does Michael have?' Encourage students to write down the numbers, draw pictures, or use manipulatives (like base ten blocks) to help them solve the problem. Have them explain their thinking to a partner.
  • Wrap-up (5 mins)
    Review the key steps in solving addition word problems. Remind students to read the problem carefully, identify the numbers, and decide whether to add or subtract. Discuss the importance of checking their answers.

Interactive Exercises

  • Spin the Wheel Game
    Create a simple spinner with numbers on it (e.g., 10-50). Have students spin the wheel twice and then add the two numbers together. They can work in pairs and check each other's work.
  • Story Time Math
    Read a short story with simple addition word problems embedded in the text. Have students identify the word problems and solve them as you read.

Discussion Questions

  • What do we need to do first when we see a word problem?
  • How does knowing about tens and ones help us add big numbers?
  • How can we check if our answer makes sense?

Skills Developed

  • Problem-solving
  • Addition
  • Place Value
  • Critical Thinking

Educational Standards

CCSS.Math.Content.1.OA.A.1:Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. CCSS.Math.Content.1.NBT.C.4:Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten. CCSS.Math.Content.1.OA.C.6:Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
