Counting with Physical Patterns
The teacher begins the lesson by holding up blocks of different colors and asking the students, "How do we see patterns in the world around us?" After discussing examples like stripes on clothes or tiles on a floor, the teacher demonstrates an alternating red-blue block pattern, counting each block aloud with the class. Students are then divided into small groups, where they receive blocks and toys to create their own patterns. As they work, the teacher circulates, asking questions like, "How many blocks are in your pattern?" and "What comes next in your sequence?"
After completing their patterns, students present their work, explaining how they used counting to ensure the pattern repeats. The teacher wraps up with a discussion on how organizing objects helps us understand numbers, connecting the activity to everyday tasks like organizing books or creating designs.
Objective:
Students will practice counting and pattern recognition by creating visual patterns and sequences using physical objects. Through this activity, students will improve their ability to count objects and identify patterns, laying the foundation for computational thinking and early math skills.
Materials Needed:
Blocks, counters, or small toys (in different colors or shapes)
Chart paper or whiteboard for group discussion
Markers for drawing patterns
Steps:
Introduction:
Begin by discussing counting and patterns with the class, asking, "How do we see patterns in everyday life?"
Use physical objects like blocks to demonstrate a simple pattern, such as alternating red and blue blocks.
Count the blocks together as a class, emphasizing how patterns help us organize and understand numbers.
Group Activity:
Divide students into small groups and provide each group with a set of physical objects like counters, blocks, or toys.
Explain that their task is to create a pattern with the objects, such as alternating colors or shapes.
Ask them to count how many objects they use in total and ensure that their pattern repeats in a logical sequence.
Creating Patterns:
Have students start arranging their objects in a simple sequence, such as alternating between red and blue blocks or lining up different shapes.
Encourage them to think about how to keep the pattern consistent and how to count the objects as they go along.
They can make patterns in rows, circles, or other shapes, as long as the sequence is clear.
Testing and Refining:
Once students complete their patterns, have them check their work by counting the objects and reviewing whether their sequence repeats correctly.
Encourage them to refine their patterns if necessary by adding or removing objects to improve the consistency of the pattern.
Presentation and Discussion:
Each group will present their pattern to the class, explaining how they created it and how many objects they used.
Lead a discussion on how patterns help with counting and how organizing objects in a sequence makes it easier to understand numbers and quantities.
Equity and Access:
Offer different types of manipulatives for students who may need additional support, such as blocks of varying colors, shapes, or sizes. Encourage students to work together, allowing those who may struggle with creating patterns to get help from their peers.
Real-World Application:
Discuss how patterns are used in daily life, such as arranging tiles on the floor or creating patterns on clothing. Relate the patterns the students created with physical objects to these real-world examples, helping them see how pattern recognition is a useful skill outside the classroom.
CS Practice(s):
Creating Computational Artifacts: Students create physical patterns, practicing early computational thinking by arranging objects in a logical sequence.
Testing and Refining Computational Artifacts: Students check and refine their physical patterns to ensure that the sequence is accurate and consistent.

Counting with Digital Patterns
The teacher begins by showing the class a simple pattern made with colored blocks, asking, "Where do you see patterns in your life?" After discussing examples like stripes on clothes or designs in nature, the teacher introduces ScratchJr on the tablets, explaining how students will create their own digital patterns. Students work in small groups, dragging and dropping animal or shape blocks into sequences, such as alternating cats and dogs. As students test their patterns in ScratchJr, the teacher circulates, asking questions like, "How many animals are in your pattern?" and "What happens if you repeat the sequence?"
After refining their work, each group presents their digital pattern to the class, explaining how they used counting and coding to create it. The teacher concludes with a discussion about how using technology helps us visualize math concepts like counting and repetition, linking the lesson to real-world examples of pattern use in everyday life.
Counting with Digital Patterns
Objective:
Students will practice counting and pattern recognition by using digital tools to create visual patterns and sequences. Through this activity, students will learn to count objects and identify patterns, laying the foundation for computational thinking and early math skills.
Materials Needed:
Tablets or computers with ScratchJr installed
Physical objects for counting (e.g., blocks or counters)
Chart paper for pattern and counting review
Steps:
Introduction:
Begin by discussing counting and patterns with the class, asking, "How do we use patterns in everyday life?"
Show examples of patterns using physical objects, like blocks arranged in alternating colors, and count them together as a class.
Group Activity:
Divide students into small groups and introduce them to ScratchJr.
Explain that they will use the app to create patterns with digital objects, such as animals or shapes.
First, students will practice counting objects on the screen and then use blocks of code to repeat these objects in a pattern (e.g., alternating animals or colors).
Creating and Coding:
Demonstrate how to drag and drop coding blocks in ScratchJr to create a sequence.
For example, show how to place a dog, then a cat, and repeat the sequence using loops.
Encourage students to create their own patterns using different objects or colors, thinking about how to arrange the objects in a logical order.
Testing and Refining:
Have students test their digital patterns by running the code in ScratchJr, checking if the objects appear in the correct sequence and quantity.
Allow time for students to refine their patterns, adjusting the order, colors, or repetition as needed.
Presentation and Discussion:
Each group will present their digital pattern to the class, explaining how they used counting and coding to create it.
Lead a discussion on how the patterns help with counting and how technology, like ScratchJr, helps us visualize and understand mathematical concepts like repetition and grouping.
Equity and Access:
Offer printed pattern guides or physical objects for students who may need additional support before moving to the digital activity. Encourage peer support, where students can collaborate and share ideas, ensuring all students can engage in the activity at their own pace.
Real-World Application:
Discuss how patterns are used in daily life, such as creating designs on clothing or arranging items in a grocery store. Relate the digital patterns to real-world examples, helping students see how computational thinking applies beyond the classroom.
CS Practice(s):
Creating Computational Artifacts: Students create digital patterns using ScratchJr, practicing early coding concepts like sequencing and loops.
Testing and Refining Computational Artifacts: Students test their ScratchJr projects and make adjustments to improve their patterns and counting accuracy.
