Below are some Math Works methods for utilizing homework. Suggested Homework Procedures: o Check homework every night o Give students an opportunity to revise homework o Start the homework assignment together at the beginning or end of class. o Dedicate 10 minutes to going over 2-5 problems that students are having trouble with (they pick some, you pick some). Model how you work through the problems on the board. o Reward students for doing homework and revising it. Homework Tips: o Homework should consist primarily of skills that students have already been exposed to. Skills should cycle in and out depending on what your students have been taught AND what they have mastered. o Require students to show their work on homework problems, not just write the answer. Give credit only when there is work. o Circulate throughout the classroom while talking about homework problems to be sure students are writing down what you are talking about and are showing work. o At the beginning of the year, homework should consist of skills taught in the previous grade level.

How can the fractional parts of a set be modeled? How can fractions be modeled using numerals, regions, sets, and number lines? When is it appropriate to use fractions? A fraction is an EQUAL part of a whole or EQUAL part of a group. The numerator is the number of equal parts you have or want; the denominator is the TOTAL number of equal parts in the whole. A mixed number is a whole number and a fraction. ESSENTIAL QUESTIONS CONCEPT KNOWLEDGE AND PROCESS ERROR INTERVENTION IF students confuse the THEN consider using the mnemonic that the denominator numerator and denominator Baltimore City Schools – Office of Mathematics [email protected] means down.

How are the numerator and denominator related? How can the fractional parts of a set be modeled? How can fractions be modeled using numerals, regions, sets, and number lines? When is it appropriate to use fractions? A fraction is an EQUAL part of a whole or EQUAL part of a group.

Fractions represent parts of a whole or group. Fractions can be compared using a variety of models. What strategies can be developed to show computation with fractions? How are models used to show how fractional parts are combined or separated? How can fractions be modeled using numerals, regions, sets, and number lines? A fraction is an equal part of a whole or part of a group (set). The numerator is the number of equal parts you have or want; the denominator is the TOTAL number of equal parts in the whole. ESSENTIAL QUESTIONS CONCEPT KNOWLEDGE AND PROCESS ERROR INTERVENTION IF students add both the numerator and denominator IF students add both the numerator and denominator Baltimore City Schools – Office of Mathematics [email protected] THEN consider emphasizing repeatedly that the denominator stays the same when you are adding and subtracting like denominators.

If subtracting, they should cross out the part that needs to be taken away. THEN consider having students line up the problem vertically with one column for the fraction and one column for the whole number. This should help them stay organized.

Probability can be represented numerically and graphically. How can the possible outcomes for an event be determined? How is probability represented numerically? How is the likelihood of an event determined and communicated? ESSENTIAL QUESTIONS CONCEPT KNOWLEDGE AND PROCESS Probability is the chance or likelihood of something happening. Probability can be written in terms of certain [WILL ALWAYS HAPPEN], impossible [WILL NEVER HAPPEN], less likely, more likely, or equally likely. ERROR INTERVENTION IF students forget to write probability as a fraction (e.g., they simply write the number of favorable outcomes) IF students forget that adding or taking away objects changes the denominator and may change the numerator IF students write the fraction as the number of favorable outcomes over the number of remaining objects instead of the number of total outcomes Baltimore City Schools – Office of Mathematics [email protected] THEN consider modeling this error for them and create a process chart for finding the probability with probability itself written as a fraction. Example: proba Bility THEN consider requiring that students draw pictures to show items that are added or taken away.

Statistical measures provide a numeric picture of the shape of the data. In what ways can sets of data be represented by statistical measures? How can the mean, median, mode, and range be used to describe the shape of the data? How can range, median, and mode be computed and compared? ESSENTIAL QUESTIONS CONCEPT KNOWLEDGE AND PROCESS Median is the middle number in a set of ordered data. Mode is the number that occurs the most often in a set of data. Range is the difference between the greatest number and the least number in a set of data. ERROR INTERVENTION IF students attempt to find the median, mode, and range without ordering the numbers from least to greatest IF students do not remember the definitions of median, mode, and range IF students have trouble finding the median when there is an event amount of data Baltimore City Schools – Office of Mathematics [email protected] THEN consider requiring that they order the numbers from least to greatest before they solve the problem. THEN consider thinking of creative ways to teach the meanings of the words: Median: the median is the middle barrier on a street; draw three shirts (small, medium, and large) and label the middle one with an M for median and middle. Mode: most often in data; relate the mode to what’s in style. Median, mode, and range rap THEN consider having them “spread out” the missing numbers between the two middle numbers and then find the median.
