PRODUCT DESCRIPTION

FIRST of all, there are 8 topics included and 4 worksheets where they have 25, 20, 15 and 10 problems per topic respectively.

SECOND, these have been some of my favorite drills that I do with my secondary school at-risk students who never learned arithmetic. You can project these materials onto the whiteboard, construct your own templates on the whiteboard or just use these materials every so often. I use them all:

1. PRIME factorization drills are handy to get students used to thinking in terms of multiplication and prime factors. This is invaluable when dealing with fractions and algebra.

2. DIVISION by powers of 10 (and some multiples of 10) can be useful after explaining how easy it is to do this based on the decimal system's beauty!

3. MULTIPLYING a 2-digit number by a 1-digit or 2-digit number mentally is one of the easiest ways to instill a sense of fun and accomplishment in young students (trust me--this works even for at-risk older kids). I include a template for this purpose and if it is not clear enough to you I will explain it in total detail if you prefer. In any case, this is MY FAVORITE exercise to do with students.

4. COMPARING FRACTIONS can be very though provoking and many different approaches can be used. To incorporate this exercise or one similar to it as part of your approach to the NF domain can be very stimulating.

5. DOUBLING and HALVING the 2 multiplicands in order to more easily accomplish mental math!

6. CONVERTING mixed numbers to improper fractions abd vice-versa is also a very worthwhile exercise or drill. I just go up and down the rows of kids and have them all do this multiple times.

All in all, these are some of my favorite drills. The students end up being proud of themselves. Take a look at the PREVIEW and you will get a good idea of the rest.

[The problems in All WORKSHEETS and PREVIEWS are printed in difficulty (1 [easy], 2 [not so easy], 3 [proficiency] up to 4 [mastery]) order within a skill. The actual difficulty level appears slightly to the left of the DK box of each problem in a very small font. Also, instructional references appear on worksheets but are optional on quizzes.]
