Measures of Central Tendency and Spread
Students will calculate and interpret mean, median, mode, range, interquartile range, and standard deviation.
Key Questions
- Compare the strengths and weaknesses of different measures of central tendency.
- Analyze how outliers affect various measures of central tendency and spread.
- Justify the choice of a particular measure of spread for a given data set.

About This Topic
World War I: Neutrality to War covers the factors that led the United States to abandon its policy of isolationism and enter the Great War. This topic examines the impact of submarine warfare, the Zimmerman Telegram, and the ideological goal of 'making the world safe for democracy.' Students also analyze the massive mobilization on the home front and the significant impact of the war on civil liberties, particularly through the Espionage and Sedition Acts.
For 11th graders, this topic is essential for understanding the shift in American foreign policy and the tension between national security and free speech during wartime. It highlights the power of government propaganda through the Committee on Public Information. Students grasp these complex geopolitical and social shifts faster through structured debates on entry into the war and collaborative investigations into wartime propaganda.
Active Learning Ideas
Formal Debate: Was War Justified?
Students debate whether the U.S. should have entered the war in 1917. They must use evidence like the Lusitania sinking and the Zimmerman Telegram, while also considering the arguments of those who wanted to remain neutral.
Inquiry Circle: The Propaganda Machine
Small groups analyze posters and films created by the Committee on Public Information. They must identify the techniques used to build support for the war and to 'demonize' the enemy, discussing the impact on German-Americans.
Think-Pair-Share: Schenck v. United States
Students read about the 'clear and present danger' test established by the Supreme Court. They work in pairs to discuss whether the government should be allowed to limit free speech during a national crisis.
Watch Out for These Misconceptions
Common MisconceptionThe U.S. entered the war immediately after the sinking of the Lusitania.
What to Teach Instead
The U.S. waited nearly two years after the Lusitania before declaring war. A 'timeline of escalation' activity helps students see the slow and deliberate shift from neutrality to intervention.
Common MisconceptionThe entire country was united in support of the war.
What to Teach Instead
There was significant opposition from socialists, pacifists, and some immigrant groups. Peer-led analysis of anti-war speeches helps students understand the level of dissent that led to the Sedition Acts.

Planning templates for Mathematics
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.
