Fun with Numbers

Overview

This 10-minute mini-lesson is designed for Year 1 students, specifically tailored to support a child with dyscalculia in exploring addition and subtraction in a practical, visual, and tactile way. The activities emphasize hands-on learning and align with the California Common Core Standards for Mathematics for Grade 1, particularly:

• 1.OA.A.1: Use addition and subtraction within 20 to solve word problems.
• 1.OA.C.6: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.

This is an inclusive and differentiated lesson that uses manipulatives, visual cues, and fun while reinforcing a strong foundation in numeracy.

Learning Objectives

• Recognize and solve simple addition and subtraction problems within 10.
• Use tangible objects and visual aids to support problem-solving.
• Build confidence by developing basic number sense in an accessible and engaging way.

---

Materials Needed

• A worksheet tailored for dyscalculia (provided below).
• 10 small plastic counters (or coins, buttons, pom-poms).
• A colourful number line (0–10).
• A whiteboard and marker (for the teacher).
• “Magic Math Cards” (pre-prepared simple index cards with 1-digit numbers and a "+" or "–" symbol).

Lesson Sequence

1. Warm-Up (2 minutes)

Topic: Counting Practice with Hands

• Begin by asking the student to wiggle their fingers. Play a quick counting game: “Show me 4 fingers. What if we add 1 more finger? Now, how many do you have?”
• Continue this with a few simple prompts, using fingers as physical manipulatives. For example: “Let’s subtract 2 fingers. How many now?”
• Build enthusiasm with positive reinforcement: “Great job! You’re amazing at counting!”

2. Direct Instruction (3 Minutes)

Focus: Visual and Tactile Addition/Subtraction

• Model using counters and the number line to solve simple problems. For instance:

  1. Lay out 3 counters.
  2. Add 2 counters.
  3. “How many counters are here now? Let’s count them together: 1, 2, 3, 4, 5! That’s 3 + 2 = 5.”

• Repeat the process with subtraction:

  1. Start with 5 counters.
  2. Take away 2 counters.
  3. “Let’s count what we have left: 1, 2, 3! That’s 5 - 2 = 3.”

• Introduce the colourful number line:

  • Show the student how to “jump forward” for addition and “hop backward” for subtraction.

• Keep instructions short, engaging, and guided by visual and physical aids to minimize cognitive overload.

3. Guided Practice (3 Minutes)

Activity: Magic Math Cards

• Shuffle a few “Magic Math Cards” with simple problems written on them, like “4 + 2” or “6 – 3.”
• Have the student pick a card, then solve the problem using counters and the number line for support.
• Example: “You picked ‘7 - 4.’ Let’s use our magic counters to figure this out!”
• Guide them through each solution, encouraging step-by-step thinking.

Differentiation Tip for Dyscalculia:

• Colour-code addition problems in green and subtraction problems in red for clarity.
• Gently acknowledge and provide encouragement if the student struggles. (“It’s okay to take your time! You’re doing great thinking about this!”)

4. Independent Practice & Wrap-Up (2 Minutes)

Worksheet: Use the following tailored worksheet.

Math Worksheet

Instructions: Use your counters or number line to help you solve these problems. You can draw or colour in the answers!

1. 3 + 1 = __
2. 5 - 3 = __
3. 2 + 4 = __
4. 6 - 2 = __
5. 4 + 2 = __
6. 7 - 1 = __

Bonus Challenge: Colour 7 counters red. Then, take away 3 counters. How many are left? __

• Before finishing the lesson, revisit one solved problem together to reinforce confidence and understanding.

---

Assessment

Success will be observed through:

1. The student’s ability to solve at least 4 out of 6 questions on the worksheet with visual supports.
2. Increased confidence in verbalizing addition/subtraction solutions with counters or the number line.

Notes for Teachers

• Keep the pace slow with encouraging, clear language.
• Be patient and allow ample think time, as dyscalculic students may need extra moments to process.
• Avoid overloading the student with too many examples; quality over quantity ensures better retention for younger learners.
