Bridges Math
Unit 1 - Expressions, Equations, & Volume
What Students Will Learn:
How to read and write math expressions
ex. 3 x (4 + 5)
Using the correct order of operations (PEMDAS)
Solving simple math problems with a letter or symbol (called a variable)
Finding and continuing number patterns
Using tables to show patterns and relationships
Understanding volume as the space inside a 3D object (like a box)
Using formulas to find volume
(length x width x height)
Solving word problems about volume
Explaining how they solve problems
Using numbers, models, and words to show their thinking
Why This Unit Is Important:
This unit helps students build strong math habits, understand algebra basics, and solve real-world problems using volume. It sets the stage for more complex math later in the year.
Earth Systems
In this unit, students explore how different parts of the Earth work together and affect each other. They learn that Earth is made up of four main systems that are always interacting.
The Four Earth Systems:
Geosphere – The solid parts of Earth
(rocks, mountains, land, etc.)
Hydrosphere – All the water on Earth
(oceans, rivers, lakes, rain)
Atmosphere – The air and gases around Earth
(weather, clouds, wind)
Biosphere – All living things
(plants, animals, people)
What Students Will Learn:
How these systems interact (Example: How rain from the atmosphere affects the land)
How natural events (like earthquakes or hurricanes) change Earth’s systems
How human activities can affect the Earth, like pollution or farming
How to use models and data to show how the Earth systems work together
Why This Unit Is Important:
This unit helps students understand how Earth works as a system. It also encourages them to think about how people affect the planet and how we can take care of it.
