TeacherBrooke Brackney
Subject AreaMath/Science/Social Studies
Grade Level4
Week #13
Unit of InstructionUnderstanding Fraction Equivalence and Comparison/Properties of Matter/Florida Explorers
Standard(s) Taught



Explain why a fraction a/b is equivalent to a fraction (n x a)/(n x b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.


Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the result of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.



Measure and compare objects and materials based on their physical properties including: mass, shape, volume, color, hardness, texture, odor, taste, attraction to magnets.


Explore the Law of Conservation of Mass by demonstrating that the mass of a whole object is always the same as the sum of the masses of its parts.


Identify properties and common uses of water in each of its states.

Social Studies


Identify explorers who came to Florida and the motivations for their expeditions

Learning Targets and Learning Criteria


Students will:

explain, using visual representation, how and why fractions can be equivalent even though the number and size of the parts are not the same.

recognize and generate equivalent fractions by partitioning number lines, rectangles, squares, and circles using visual models.

explain that fractions can only be compared when they refer to the same sized whole (e.g., 1/ 2 of a small pizza is not the same size as 1 /2 of a large pizza.)
NOTE: Denominators limited to 2, 3, 4, 5, 6, 8, 10, 12, 100.

compare two fractions with different numerators and different denominators by: o using benchmark fractions (e.g., 5/ 8 is close to 1 /2 and 1/ 10 is close to 0, therefore 5/ 8 > 1 /10 ).

using visual models to create fractions with common numerators or common denominators.

record the results of comparisons with the symbols <, > or =

justify the conclusions of comparisons


Students will:

compare objects based on observable and measurable physical properties (shape, color, hardness, texture, odor, taste, attraction to magnets, mass, volume, temperature).

investigate and explain that all matter has the following measurable properties: volume (takes up space) and mass (weight).

record and compare the volume of regular- and irregular-shaped solids using the water displacement method.

display data appropriately in charts, tables, and graphs.

compare measurement data with other lab groups checking for accuracy.

explain any differences that may have occurred across groups. 

investigate and describe properties of water in all three states

identify common uses of water in all three states.

Social Studies

Students will be able to:

Identify explorers who landed in Florida

Explain why explorers came to Florida and the outcomes of their expeditions
