SequencesLessonsMaterialsVideos

Counting sequences, place value systems, and the four mathematical operations across whole numbers and decimals. Builds proficiency in solving equations, identifying numerical patterns, and applying properties of operations to multi-digit arithmetic.

Counting SequenceSequential number naming and cardinal counting principles for early learners. Develops fluency in forward and backward sequences while introducing skip-counting patterns.
Numbers 0-10Numeral recognition, counting, and cardinality for integers zero through ten. Strengthens one-to-one correspondence and basic number sense through visual sets and tracing.
Addition and Subtraction ConceptsMental math strategies, regrouping techniques, and the inverse relationship between operations. Builds computational fluency through visual models, number lines, and real-world word problems.
Patterns and RelationshipsIdentification, extension, and creation of repeating and growing patterns using shapes, colors, and numbers. Develops algebraic thinking by analyzing sequences and defining functional relationships between variables.
