Students investigate division as sharing by splitting a unit fraction into equal parts among a whole number of groups.

Students explore division as measurement by determining how many unit fractions fit into a whole number using visual models.

A week-long series of activities focused on identifying math operations in word problems, counting mixed coins, and determining if a purchase is affordable within a budget. Includes a teacher guide, graphic organizers, and practice worksheets themed around a neighborhood corner store.

A cumulative review and assessment of ratio and rate concepts through a 'Lab Challenge'.

Students solve complex, multi-step ratio problems using a variety of visual models.

Students find the whole given a part and the percent, or find the part given the whole and percent.

Students define percent as a rate per 100 and represent percents using 10x10 grids.

Students solve problems involving constant speed using unit rates and ratio reasoning.

Students apply unit rate reasoning to find the 'better buy' in shopping scenarios.

Students transition from ratios to unit rates, understanding the concept of 'per 1'.

Students use double number lines to solve ratio problems involving distance, time, and scaling.

Students organize equivalent ratios into tables to identify patterns and solve problems.

Students explore equivalent ratios using simple multiplication and division strategies.

Students use tape diagrams to represent part-to-part and part-to-whole relationships visually.

Students learn to use ratio language to describe a relationship between two quantities. Focus on "for every" language and identifying parts and wholes.

A professional development suite for school leaders focused on increasing math instructional intentionality. This lesson provides tools for auditing schedules, coaching lesson internalization, and refining small-group instruction to foster student agency.

A lesson focused on comparing quantities and numbers up to 15 using visual representations and numerical values. Students will practice identifying sets with more or fewer items and comparing numerals directly.

Forward sequences and numeral identification for numbers 50-100.

Placing and identifying numbers on an open number line (0-50).

Backward sequences across decades (50 down to 20).

Mastering transitions between decades from 20 to 50.

Intensive focus on backward number sequences from 20 down to 10.

Focus on numeral identification and forward sequences for numbers 11-20.

Consolidation of skills where students compare varied pairs of two-digit numbers and record results using appropriate symbols and mathematical reasoning.

Focusing on numbers where the tens digits are different, emphasizing that the tens digit is the primary factor in determining which number is greater.

Focusing on numbers with the same tens digit to understand that when tens are equal, we look at the ones digit to determine the relationship.

Introduction of the symbols <, >, and = as tools to record the relationship between two numbers, connecting them to the language of 'greater than' and 'less than'.

Students compare two numbers visually using base-ten models to identify which is 'greater' and which is 'less' before introducing formal symbols.

Students build two-digit numbers using base-ten models to understand that the tens digit represents the number of groups of ten and the ones digit represents the number of leftovers.

Synthesizes all lab skills to solve word problems and create original equations. Students prove their mastery as Lead Equation Scientists.

Develops strategies for finding an unknown part in an equation. Students use part-whole models to solve for the 'missing component' in both addition and subtraction contexts.
