An inquiry-based exploration of number naming patterns from tens to millions, helping 2nd graders see the repeating linguistic structures in large numbers through a 'detective' lens.
This sequence guides 2nd-grade students through the process of reading and writing number names up to 1,000, focusing on tricky spellings, hyphenation rules, and correct syntax for three-digit numbers.
A 2nd-grade sequence where students act as 'Code Breakers' to master reading and writing large number names by identifying repeating patterns and the function of the comma as a 'period' signal.
A 5-lesson sequence for 2nd graders focused on reading, writing, and spelling number names from 0-99, with special attention to hyphenation and phonetic distinctions.
This sequence explores the extension of the counting sequence from 100 up to 1,000, focusing on century boundaries and the recursive nature of the base-ten system. Students use concrete models and charts to master the patterns of numbers in the hundreds.
A comprehensive 2nd Grade unit focusing on skip counting by 2s, 5s, 10s, and 100s up to 1,000. Students explore patterns on hundreds charts, use manipulatives for grouping, and apply strategies to count large collections efficiently.
Students move beyond the 1-100 count to 120, identifying repeating patterns of ones and tens. The sequence covers chart structure, the transition past 100, numeral notation, and sequencing through hands-on and collaborative activities.
A 12-session math intervention unit for Tier 3 students, focusing on place value up to the hundreds, addition and subtraction within 20, and single and two-step word problems.
Une série de leçons fondamentales pour les élèves de CE1, couvrant les mathématiques (nombres de 0 à 100) et le français (identification du sujet dans la phrase).
A comprehensive diagnostic suite for grades 2-5 designed to identify specific skill gaps in foundational math domains aligned to the Iowa Core standards. This series helps educators pinpoint exactly where students have discrepancies in place value, arithmetic, and early rational numbers.
A comprehensive set of progress monitoring probes focused on 2nd and 3rd-grade number sense and fractions for 4th-grade students working on foundational skills.
A comprehensive 16-lesson unit focusing on mental math strategies for subtraction within 20, themed around Team USA's journey to gold in the Winter Olympics.
A targeted Tier 2 intervention sequence for 2nd graders focusing on 3-digit place value, progressing from concrete models to abstract representation and comparison.
A collection of Valentine's Day math packets at two different levels (Level 1 and Quest), covering budgeting, graphing, measurement, time, and word problems.
A 10-lesson intensive unit for 2nd Grade focusing on high-leverage place value and operations concepts (IM Units 4 & 5), using an architectural blueprint theme to build conceptual understanding of numbers up to 1,000.
A foundational sequence for 2nd-grade students exploring the concepts of equality, equilibrium, and balancing equations using physical scales and numerical equivalents. Students progress from physical balance to symbolic representation using the equal sign.
A high-energy sequence for 2nd graders to build fluency in multiplication and division through skip counting, grouping, and identifying number patterns using a sports-training theme.
A game-based sequence where 2nd-grade students build fluency in comparing and ordering three-digit numbers through strategic digit placement, number line visualization, and tournament-style competitions.
This sequence focuses on extending student fluency with the counting sequence up to 120, emphasizing both forward progression across decade transitions and backward counting from various starting points. Students use number lines and 120 charts to visualize number order and solve sequence problems.
A three-day unit for 2nd and 3rd graders focused on comparing two and three-digit numbers using place value reasoning and comparison symbols (>, <, =). Students move from hands-on conceptual building with blocks to symbolic representation and independent assessment.
A 3-part sequence for small groups focusing on comparing numbers up to 150 using the hungry alligator analogy. Students will progress from basic comparisons to place value understanding and real-world applications.
