Multiplying Integers
Students will develop and apply rules for multiplying positive and negative integers.
Key Questions
- Why does multiplying two negative numbers result in a positive product?
- Explain the pattern of signs when multiplying multiple integers.
- Predict the sign of a product involving an odd or even number of negative factors.
Common Core State Standards
About This Topic
Post-Soviet Russia & Central Asia explores the massive geographic and political shifts following the 1991 collapse of the USSR. Students examine the transition from a command economy to a market-based one and the challenges of governing the world's largest country by land area. The unit also highlights the diverse cultures and resources of Central Asian nations like Kazakhstan and Uzbekistan as they forge their own identities.
This topic is vital for understanding current events and the role of natural resources in global power. It aligns with standards regarding the impact of political changes on geographic boundaries and economic systems. This topic comes alive when students can physically model the patterns of resource distribution and the logistical hurdles of Russia's eleven time zones.
Active Learning Ideas
Inquiry Circle: The Time Zone Challenge
Groups are given a scenario where a business in Vladivostok needs to communicate with an office in Moscow. They must use a time zone map to plan a schedule and identify the logistical difficulties of operating across such a vast distance.
Think-Pair-Share: Command vs. Market Economies
Students compare a list of how goods are produced and priced in both systems. They discuss with a partner which system they think is more efficient and what the 'growing pains' of switching might look like.
Gallery Walk: The New Map of Central Asia
Display maps and cultural profiles of the 'Stans' (Kazakhstan, Kyrgyzstan, etc.). Students rotate to find one unique resource and one cultural tradition for each country, noting how they differ from Russia.
Watch Out for These Misconceptions
Common MisconceptionRussia is mostly a frozen wasteland.
What to Teach Instead
While much of Russia is cold, it has diverse biomes including forests (taiga), grasslands (steppes), and even subtropical areas. Using a 'Gallery Walk' of climate zones helps students see this diversity.
Common MisconceptionThe transition to a market economy was easy and fast.
What to Teach Instead
The shift in the 1990s led to significant economic hardship, inflation, and the rise of oligarchs. Peer discussion of 'before and after' scenarios helps students understand the social cost of rapid political change.

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.
