An out-of-this-world fourth-grade lesson on adding and subtracting fractions with like denominators. Students join and separate precious crystal shards on fractional meteors to master combining parts of a whole.

A mastery-focused lesson pack designed to teach, assess, and practice 3-digit addition and subtraction using base-ten drawings, expanded form, and the standard algorithm. Includes a comprehensive rubric, student exemplar exemplars, and a multi-strategy practice worksheet.

A high-engagement 6th-to-7th grade bridge lesson that connects ratio tables and graphing (NY-6.RP.3a) to the constant of proportionality and proportional relationships (NY-7.RP.2). Students act as detectives solving blueprint puzzles using coordinate planes and ratio analysis.

A hands-on, high-engagement lesson where 4th-grade students distinguish between additive and multiplicative comparison using visual models, tape diagrams, and real-world toy factory scenarios. This lesson includes interactive presentation slides, a student matching activity, and a comprehensive teacher guide.

A focused check-for-understanding assessment on 3-digit subtraction with regrouping, including subtracting across zeros and solving for missing numbers using inverse operations.

A math lesson focused on building single-digit multiplication and four-digit addition fluency while integrating self-regulation check-ins to foster a growth mindset.

An engaging elementary math lesson focused on adding and subtracting money, lining up decimals, regrouping across zeros, and solving real-world shopping word problems up to $10.00.

Days 16-20 of the review, focusing on integrating operations, fractions, decimals, and geometry to solve complex multi-step real-world word problems (OA.3).

Days 11-15 of the review, focusing on identifying geometric attributes, lines, angles, 2D shapes, and line symmetry (G.1 through G.3).

Days 6-10 of the review, focusing on Decimal notation, fraction equivalence with tenths and hundredths, and comparing decimals (NF.5 through NF.7).

Days 1-5 of the review, focusing on Fraction equivalence, comparing, addition, subtraction, and multiplication of fractions (NF.1 through NF.4) through workshop rotations.

A stations-based decimal addition and subtraction activity where students rotate through virtual storefronts to buy school supplies, tech, sports gear, and room decor within a set budget.

Students explore and master the Marley Park Elementary STAR expectations for 5th-grade leaders. Through scenario analysis, modeling, and justifying correct and incorrect behaviors, they prepare to set a positive example for the school.

Students learn to translate word phrases into numerical expressions and interpret expressions without evaluating them, building critical algebraic reasoning skills for subsequent grades.

Students master the order of operations, including parentheses, brackets, and braces. They learn to evaluate numerical expressions systematically, modeling calculations like structural blueprints.

Students transition from concrete partial quotients to standard long division steps, solving problems with up to four-digit dividends and two-digit divisors. Emphasizes interpreting remainders in real-world contexts and debugging calculation steps.

Students connect conceptual area models to standard multi-digit multiplication, developing procedural fluency with the standard algorithm while maintaining strong place value understanding. Includes error analysis and architectural design challenges.
