Subtraction Safari

A targeted 3-lesson intervention sequence designed to build foundational number sense, number line reasoning, and visual operation models for 6th graders working below grade-level proficiency. Emphasizes concrete-representational-abstract progressions, visual anchors, and low-floor entry points to build mathematical confidence.

A 45-minute small-group math lesson for 2nd grade focused on decomposing hundreds into tens using place value disks, bridging concrete manipulation to representational place value charts.

A 2nd grade math exit ticket with significantly larger drawing boxes for showing numbers (130 and 200) in two different ways using place value disks.

A two-part sequence exploring segment addition, subtraction, and midpoint relationships through visual GCR deductive reasoning and algebraic modeling.

A 45-minute small-group math intervention lesson focused on teaching 2nd-grade scholars how to verbally rehearse and write rigorous math explanations using the RACE framework and MOLE problem-solving habits. Emphasizes heavy teacher modeling, oral discourse, and structured sentence stems.

Updated 2nd grade math worksheet with consistent, significantly larger drawing boxes for all place value charts and Do Now problems, and removed the math talk section on page 2.

A targeted two-day intervention sequence focused on 4th-grade addition and subtraction word problems with whole numbers using strip diagrams and the standard algorithm. Covers Add To Unknown, Result Unknown, and Mixed Problem scenarios.

A 45-minute second-grade mathematics lesson designed to help students master determining 1 more, 1 less, 10 more, and 10 less using concrete base-ten models, place-value charts, highlighted digits, and arrow notation. The lesson preserves the original place-value Do Now while scaffolding student understanding from concrete manipulatives to mental math fluency within 200.

Facilitation guide for a 45-minute small group lesson plan, aligned with the enlarged box layouts and focused practice on representing 3-digit numbers in two different ways.

A three-day targeted math intervention sequence for third-grade resource groups focused on mastering standard algorithm addition and subtraction with multi-step regrouping. Students practice with structured place-value organizers that provide ample handwriting room.

A targeted 45-minute first-grade math lesson that develops foundational place value understanding by composing and decomposing two-digit numbers into tens and ones using base-ten models, place value charts, and number bonds.

A revised 2-page 2nd-grade student practice worksheet featuring an interactive visual RACE checklist at the top of each page, a single large blank MOLE strategy box, and primary handwriting lines with headline, midline, and baseline for student responses.
