Synthesizes all skills to compare decimal fractions and solve real-world context problems. Students use comparison symbols and order decimals, concluding the 'Precision Press' investigative series.

Connects fraction notation (tenths and hundredths) to decimal notation (0.1 and 0.01). Students learn to write 3/10 as 0.3 and 3/100 as 0.03, reinforcing the place value relationship between the two.

Develops the procedural fluency of adding fractions with unlike denominators (10 and 100) by converting tenths to hundredths first. Students solve problems using the common denominator method without relying solely on visual models.

Introduces addition of fractions with denominators 10 and 100 using visual models. Students shade tenths and hundredths on the same grid to understand why common denominators are necessary for addition.

Transitions from visual grid models to numerical strategies for creating equivalent fractions. Students practice multiplying the numerator and denominator of a tenth-based fraction by 10 to express it in hundredths.

Focuses on visualizing tenths and hundredths using 10x10 grids to establish the foundational equivalence that 1/10 equals 10/100. Students engage in 'Notice and Wonder' routines to compare fractional representations.

Students use geometric reasoning to solve mystery riddles about shape hierarchies. By applying the process of elimination, they reinforce the understanding that subcategories inherit all attributes of their parent categories.

An immersive ocean-themed lesson for converting common fractions (halves, quarters, tenths) into decimals. Students dive into marine biology and treasure hunting while mastering decimal place value.

A lesson focused on mastering the US standard algorithm for subtraction up to the hundred thousands place using structured place value organizers. Students practice regrouping and maintaining alignment through visual grids.

Cumulative review and a 'Division Derby' game to celebrate progress and demonstrate mastery.

Solving multi-step real-world problems that require multiple division or multiplication steps.

Dividing decimals by decimals by using powers of 10 to create equivalent expressions with whole-number divisors.

Extending division to decimals by dividing a decimal by a whole number using place value reasoning.

Analyzing word problems to determine how to interpret remainders: rounding up, dropping, or using as a fraction.

Applying the partial quotients method to division problems with two-digit divisors.

Using estimation and rounding to find reasonable starting points when dividing by two-digit numbers.

Refining the partial quotients method to handle larger three-digit dividends with one-digit divisors efficiently.

Using place value patterns to divide by multiples of 10, 100, and 1,000, focusing on the movement of digits.

Introduction to the partial quotients method (The Big 7) as a way to decompose dividends into friendly chunks.
