Students also practice describing the direction of rotations as clockwise or counterclockwise and apply these concepts to determine facing directions and geometric rotations.

In this Grade 4 Saxon Math lesson, students extend their long division skills to produce three-digit quotients using the four-step pencil-and-paper method: divide, multiply, subtract, and bring down. They practice applying this process to whole numbers with remainders, dividing dollars and cents by aligning the decimal point in the quotient directly above the decimal point in the dividend, and using compatible numbers to estimate quotients.

In Saxon Math Intermediate 4, Grade 4 students learn to distinguish between mass and weight, understanding that weight depends on gravity while mass does not. The lesson covers U.S. Customary units of weight (ounces, pounds, and tons) and metric units of mass (grams and kilograms), including key conversions such as 16 oz = 1 lb, 2000 lb = 1 ton, and 1000 g = 1 kg. Students practice converting between units and choosing reasonable measurements for real-world objects.

In this Grade 4 lesson from Saxon Math Intermediate 4, students learn to classify triangles in two ways: by their largest angle (obtuse, right, or acute) and by the lengths of their sides (equilateral, isosceles, or scalene). Students also explore the relationship between equal sides and equal angles, including the concept that equilateral triangles are equiangular. The lesson extends understanding by having students draw and describe triangles that combine multiple classifications, such as a right isosceles triangle.

In this Grade 4 Saxon Math lesson from Chapter 8, students learn to identify and draw lines of reflective symmetry in polygons, letters, and other figures, and distinguish figures that have rotational symmetry from those that do not. Students use a mirror as a hands-on tool to explore how a line of symmetry divides a figure into two mirror-image halves, and they examine how figures like squares and regular polygons rotate to match their original positions at specific degree intervals. The lesson builds geometric reasoning skills through classifying shapes, uppercase letters, and real-world examples by their symmetry properties.

Grade 4 students learn how to perform long division using the four-step divide-multiply-subtract-bring down method when the quotient contains a zero in the tens or ones place, including problems that produce three- and four-digit answers with or without remainders. This Saxon Math Intermediate 4 lesson, Chapter 8 Lesson 80, uses real-world contexts such as newspaper delivery and weight in tons to practice writing zeros correctly in the middle or end of a quotient. Students also practice mental division and calculator division to compare decimal and remainder forms of answers.

Grade 4 students explore analyzing and graphing relationships in Saxon Math Intermediate 4, Chapter 8, learning how to write equations to represent data tables and plot coordinate pairs on a graph. Students practice identifying functions by connecting quantities like quiz scores and correct answers or hours worked and total pay, using multiplication formulas such as Score = Number of Correct Answers × 10. The lesson also introduces coordinate planes, where students name points using ordered pairs and use them to draw geometric figures like rectangles.
