Across
- 2. A polynomial with two terms binomial
- 4. using concrete models, tables, graphs, words, and symbols to understand and connect all other concepts.
- 5. An extension of arithmetic word-problem strategies, algebraic strategies assisted students in understanding the problem, representing the problem with diagrams and equations, following problem-solving steps, and evaluating solutions.
- 6. using dynamic platforms to develop understanding of algebraic concepts and procedures.
- 7. are the sum and/or difference of monomials and do not include negative exponents.
- 10. mathematics helps us understand the world around us through the applications of modeling, optimization, symbolism, inference, abstracting, and logical analysis.
- 11. - using the three previous key ideas, students should represent, analyze, and draw con-clusions using models.
- 13. is the processes of viewing a particular example in a more general way
- 15. which is the abstract study of number systems and their operations
- 16. In most of these games, two players take turns moving objects along lines to specific points on the board, attempting to achieve three objects in a straight line while blocking the other player from getting three-in-a-row first. Each move becomes a function of the locations available on the board as a result of previous moves.
- 18. using real-life situations to provide a problem context
- 19. involves broadening the range of applications, extending reasoning beyond specific examples
- 20. are single terms while polynomials have several terms, connected with addition or subtraction symbols.
Down
- 1. - an understanding of functions and the difference between functions and relations. Related concepts include representations of functions, rates of change, geometric progressions, and families of functions.
- 3. Some students use the mnemonic devise Please Excuse My Dear Aunt Sally to remember this sequence (parentheses, exponents, multiplication/division, addition/subtraction).
- 8. is another key concept for many areas of mathematics and can be linked to students’ prior knowledge of a hillside, a skateboard ramp, a roofline, or a wheelchair ramp.
- 9. for middle- and high-school settings
- 12. an understanding of the meaning and different possible roles of variables in expressions, equations, and inequalities. Related to this key concept are other foundational concepts of prop-erties of operations and equivalency.
- 14. refers to the number that multiplies the variable(s) in a term.
- 17. -multiple representations of patterns. Related concepts are arithmetic sequences, propor-tional relationships, and recursive patterns.
