Standards Alignment

Ohio Early Learning and Development Standards (Mathematics):

• Counting and Cardinality (K.CC):
  • K.CC.A.1: Count to 100 by ones and tens.
  • K.CC.B.4: Understand the relationship between numbers and quantities; connect counting to cardinality.
  • K.CC.B.5: Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or presented randomly.
• Common Core State Standards (Math) – Kindergarten:
  • CCSS.MATH.CONTENT.K.CC.B.4
  • CCSS.MATH.CONTENT.K.CC.B.5
• Grade 1 (for extension purposes):
  • CCSS.MATH.CONTENT.1.NBT.A.1 (Count to 120, starting at any number less than 120)

---

Learning Objectives

• I can count aloud from 1 to 20 using objects.
• I can match each object I count with one number name, pointing to each item once.
• I can answer “how many?” questions by counting objects in different arrangements.
• I can recognize when a number matches a specific quantity.

---

Success Criteria

Students will be successful when they:

• Correctly count sets of objects up to 20 using one-to-one correspondence.
• Accurately answer “how many?” questions about different groups of manipulatives.
• Confidently place objects in groups and count them without skipping or repeating.
• Show understanding by explaining how they counted and what number shows the total quantity.

Materials Needed

• Colored counting bears or small plastic animals (20 per student)
• Number cards 1–20 with clear, large print and dyslexia-friendly fonts (e.g., OpenDyslexic)
• Counting mats (with spaces/groups for objects)
• Dry erase boards and markers
• Visual number line (1–20) on display
• Baskets or containers for manipulatives

Lesson Plan Breakdown

Time	Activity	Description	Notes
0-5 min	Introduction & Goal Setting	Gather students, introduce the objective using “I can” statements on a poster. Model counting 5 bears aloud with clear finger tracking.	Use clear, slow speech and gestures to support learners with language difficulties.
5-10 min	Demonstration & Guided Practice	Show how to use counting mats and how to count objects so each is touched only once when saying the number aloud. Ask, “How many bears are here?”	Use large manipulatives so students with fine motor challenges can handle easily.
10-20 min	Math Centers Rotation (4 groups of 5 students)	1. Counting Bears Center: Count out sets of bears from the basket to match number cards. 2. Number Card Match: Match counted objects to a number card. 3. Build a Set: Teacher calls out a number 1-20, students build the set with manipulatives. 4. Partner Counting: Students take turns counting a shared set of bears, encouraging peer support.	Teacher or aide at each center for scaffolding and encouragement. Visual cues and steps posted.
20-35 min	Small Group Support	Targeted help for students needing support—re-teach with smaller groups and additional visuals.	Use simplified counting mats with fewer objects for struggling learners. Use picture cues to reinforce number names.
35-45 min	Advanced Learners Extension	Students who finish early or grasp concepts quickly: - Count backward from 20 to 1 with objects. - Count objects in groups of tens and leftovers (e.g. 12 = 10 + 2). - Practice skip counting by 2s using manipulatives.	Use challenge cards with larger numbers. Encourage students to explain their counting strategy.
45-55 min	Whole-Class Wrap-Up & Reflection	Discuss: “What was easy or hard about counting today?” Use a large number line for students to come up and point to numbers as they count aloud. Record a few students sharing their “I can” sentence.	Affirm effort and address common errors seen. Use positive language and recaps to reinforce learning.
55-60 min	Assessment & Goodbye	Exit ticket: Students draw a small set (up to 10 items) and write the number or say it aloud to the teacher.	Informal assessment to see each child’s progress.

Differentiation Strategies

Learner Needs	Strategy
English Language Learners (ELL)	Use visual aids and realia extensively; pair with bilingual buddies where possible. Say number names clearly and slowly. Use gestures and repeat directions.
Students with Fine Motor Difficulties	Provide larger manipulatives and counting mats with clearly separated spaces. Allow counting by touching mats instead of objects if preferred.
Students with Attention Challenges	Structure center times in short bursts with movement breaks. Use timer or visual countdown to help stay focused.
Students with Dyslexia or Reading Difficulties	Use dyslexia-friendly fonts on number cards and written instructions. Use pictorial supports and minimal text. Provide oral instructions and demonstrations for tasks.

Extension Activities for Advanced Learners

• Count objects beyond 20 using manipulatives — group objects in twenties and ones to reinforce place value.
• Introduce simple addition: “If we add 3 bears to 5 bears, how many do we have?” Use manipulatives to visualize.
• Introduce grouping objects by color or shape and counting each group separately.
• Create their own number cards and matching game with drawings or photos.

---

Dyslexia-Friendly Reading Options

• Use OpenDyslexic font on all printed materials and number cards.
• Large, clear print with high contrast (black text on white or off-white background).
• Keep written directions short and paired with clear visual icons or pictures (e.g., a picture of a bear next to the word “count”).
• Provide audio instructions or read-aloud options during center rotations.
• Encourage students to use finger tracking or a pointer when reading numbers or instructions aloud.

---

Reflection for Teachers

• Observe students’ counting strategies: Are they using one-to-one correspondence or guesswork?
• Note students struggling to recognize numbers versus those confident with quantities.
• Track who easily moves to extension tasks and who benefits from additional scaffolding.
• Plan follow-ups based on observed needs: more practice with cardinality, number recognition, or grouping concepts.
