Introduction & Learning Objectives

Learning Objectives Identify a simple repeating pattern. Describe the 'rule' of a pattern. Predict the next item in a sequence. Create their own simple A-B or A-B-C pattern. Explain why their prediction is correct. Find patterns in daily routines like getting ready. If you see a cat ๐Ÿˆ, then a dog ๐Ÿ•, then a cat ๐Ÿˆ... what animal comes next? ๐Ÿค” We will learn about patterns! Patterns help us guess what comes next. This is a super skill for solving puzzles and giving instructions to a computer. Real-World Applications Knowing the next step in a song ๐ŸŽต Getting dressed in the morning ๐Ÿ‘•๐Ÿ‘– Following a recipe to bake cookies ๐Ÿช Playing games like Simon Says ๐Ÿง

SequenceA sequence is a list of things in a special order. โžก๏ธ๐ŸŽ, ๐ŸŒ, ๐ŸŠ is a sequence of fruits. RuleThe rule tells us how the pattern works. It is the secret code! ๐ŸคซIn the pattern โ˜€๏ธ, ๐ŸŒ™, โ˜€๏ธ, ๐ŸŒ™... the rule is 'sun then moon'. PredictTo predict means to make a smart guess about what is next. ๐Ÿ”ฎI predict the next color will be green. StepA step is one single thing in a pattern or a set of directions. ๐ŸพThe first step is to pick up a pencil.

Core Syntax & Patterns

Look and Say Rule Say the pattern out loud. Use this first! Hearing the pattern can help you find what repeats. Find the Core Rule Find the smallest part that repeats. Look for the group of items that happens again and again. Check Your Guess Rule Does your guess follow the rule? After you predict, check if it fits the pattern you found.
