Solving Systems by Elimination (Addition)
Solving systems algebraically by adding or subtracting equations to eliminate a variable.
Key Questions
- Explain how the elimination method relies on the properties of equality.
- Analyze when elimination is the most efficient method for solving a system.
- Construct an algebraic solution to a system using the elimination method.

About This Topic
The Age of Jackson explores the transformative presidency of Andrew Jackson and the rise of 'Jacksonian Democracy.' Students learn about the expansion of voting rights to nearly all white men, the 'spoils system,' and the shift toward a more populist style of politics. The curriculum also examines the controversies of his era, including the 'Bank War' and his use of the presidential veto.
This topic is a key part of 8th-grade history as it marks the transition from the 'rule of the elite' to the 'rule of the common man.' It raises fundamental questions about the nature of democracy and executive power. This topic particularly benefits from hands-on, student-centered approaches like mock elections or structured debates, where students can evaluate whether Jackson was a 'champion of the people' or a 'king-like' tyrant.
Active Learning Ideas
Formal Debate: King Andrew or Champion of the People?
Students analyze political cartoons of Jackson, one showing him as a King trampling the Constitution and another as a hero of the common man. They debate which image more accurately reflects his presidency based on his actions.
Simulation Game: The Spoils System
The teacher 'appoints' students to classroom 'jobs' based on their loyalty to a specific 'party' rather than their skills. Students then discuss the pros (loyalty) and cons (inefficiency) of this system in a real government.
Think-Pair-Share: The Bank War
Students read Jackson's reasons for vetoing the National Bank. They discuss in pairs whether he was protecting the 'common man' from a corrupt elite or destroying a necessary part of the economy.
Watch Out for These Misconceptions
Common MisconceptionAndrew Jackson gave everyone the right to vote.
What to Teach Instead
He oversaw the expansion of voting rights for white men (by removing property requirements), but women, African Americans, and Native Americans were still excluded. A 'who can vote' chart over time helps students see the limits of this 'democracy.'
Common MisconceptionJackson was a typical politician of his time.
What to Teach Instead
He was the first 'outsider' president, born poor and from the West, which was a huge shock to the political establishment. Peer discussion on his 'common man' image helps students understand why he was so popular and so hated.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
