Add to Find Totals

Overview

In this 30-minute lesson, students use addition to solve picture-supported, real-world problems involving collections, shopping, and large quantities. They identify important information, choose addition, represent the problem with objects, drawings, or an equation, and label the total.

Learning intentions

Students will be able to:

• I can find the important numbers in a word problem.
• I can choose addition when quantities are combined.
• I can solve an addition problem using objects, a drawing, or an equation.
• I can explain and label my answer.

Success criteria

• I can circle or identify the numbers I need.
• I can choose addition because the problem asks for a total or how many altogether.
• I can calculate accurately.
• I can label my answer with what it represents.

Lesson structure (30 minutes)

1. 0–4 min · Hook and connect. Teacher displays a shopping picture showing 6 apples and 4 oranges and asks, “How many pieces of fruit are there altogether?” using the opening shopping picture. Students turn and talk, act out combining the groups with counters, and share what the word “altogether” tells them.

2. 4–10 min · I do: model a story problem. Teacher acts out, “A store has 12 red bags and gets 5 more bags,” using picture cards or classroom objects; on the teacher-model problem, the teacher reads the problem aloud, circles 12 and 5, highlights “more,” writes 12 + 5 = 17, and labels the answer “17 bags.” Students identify the numbers, explain why addition is needed, and repeat the problem-solving sequence: find numbers, choose addition, calculate, label.

3. 10–16 min · We do: build and match. Teacher presents two item cards and a “total” frame on the drag-and-build activity and models moving quantities into the frame before revealing three possible equations. Students work in pairs with counters or classroom objects to combine the quantities, choose the matching equation, and explain their choice using the sentence frame: “I added ___ and ___ because the problem asks for ___.”

4. 16–23 min · You do: solve independently. Teacher distributes the picture-supported addition practice sheet and reads each short problem aloud, pausing after students identify the important numbers. Students solve one-step problems using objects, a drawing, or an equation, then label each answer; the teacher conferences with individuals and provides adult scribing when needed.

5. 23–27 min · Share and check. Teacher displays one worksheet problem on the strategy-check slide and asks, “How did you represent the problem? How do you know your answer is reasonable?” Students compare strategies with a partner, check whether their operation and label match the story, and revise if necessary.

6. 27–30 min · Quick assessment and close. Teacher gives the five-question check on the five-question assessment section and reads each item aloud. Students select or record an answer independently, then complete the oral close: “Today I learned that the word ___ can help me choose addition.”

Resources

• the addition problem-solving slide deck
• the picture-supported addition practice sheet
• Counters, linking cubes, or other small classroom objects
• Picture cards for shopping and collection stories
• Pencils and highlighters
• Large-print copies and a document camera or interactive display
• Optional number lines for students who need a visual calculation support

Assessment

• During modeling and partner work, check whether students identify both relevant numbers, select addition, and explain the meaning of “total,” “altogether,” or “more.”
• Review worksheet representations for accurate equations, calculations, and labels. Note whether students rely on objects, drawings, or symbolic equations.
• Use the five-question check: 1) 24 + 15 = 39; 2) 2,000 + 1,000 = 3,000; 3) “altogether” often means add; 4) $35 + $20 = $55; 5) 120 + 30 = 150. Use results to plan reteaching or further practice.

Differentiation

• Support students with one-step stories, real objects, story mats, highlighted numbers, and a four-part visual prompt: “Find the numbers. Choose addition. Calculate. Label.”
• Provide sentence frames such as “I used addition because ___” and “There are ___ ___ altogether.” Offer adult scribing or allow students to explain an equation orally.
• For dyslexia-friendly access, use picture-first problems, read all text aloud, use short lines and large clear font, highlight important numbers, and avoid crowded pages. Give students extra processing time and check understanding privately.
• Challenge students who finish early to write a matching addition story for a given equation, solve it in two ways, or change one quantity and explain how the total changes.
