The sloooooow way is to simply begin scrolling page after page until I finally get there more than 200 pages into the document. Avoid the horrible scroll of death.
The FAST way is to use the search field!
Enter "Lesson 20" into the Search field. Make sure you include the quotation marks!
Then hit RETURN until you finally get to your desired page.
In this case, Lesson 20 finally began on page 274!!!
I got there in just a couple of clicks.
This will become an increasingly important skill as school districts gradually move to OER and other electronic and pdf-based curricula.

While it is true that he is struggling to memorize his multiplication facts, my real concern is that I'm not entirely sure he understands what multiplication even means. When he comes across a fact that he doesn't know, I'm not entirely sure whether he even knows of a strategy for finding the answer. It appears that his only strategy is based on skip counting. For example when confronted with...
Clearly, however, this technique is fraught with error, since each hand only has five fingers and he is attempting to repeatedly count six on his right hand, while tallying to seven on his left hand.
I believe the problem is that his teachers have tried to move my son too quickly into memorization without first ensuring he has developed the number sense necessary to achieve fluency.
Basic fact fluency requires the presence of flexibility, appropriate strategy use, efficiency, and accuracy. (I copied and pasted this from somewhere, but for the life of me I cannot find where.) Clearly, my son's single coping strategy indicates he is neither flexible nor is able to select from a variety of strategies. For example, if one does not immediately know
then perhaps skip-counting will help...
or try repeated addition using "doubles" to increase efficiency...
or try using an area model with a little bit of the distributive property thrown in...
or connect the fact to a related known division fact...
Research shows that the way to develop fluency is to increase the student's number sense.
Memorization does not increase number sense. In fact, the lowest achieving students are more likely to focus on memorization, while the highest achievers focus on strategies based on number sense.
Using this as my premise, I created a system that will give my son more strategies to use for deriving the answer to the multiplication fact if he doesn't already remember it.
- Show a flash card and silently count to five seconds. However, give as much time as he needs to answer the question. (Speed is NOT a goal at this point.)
- Place the card in one of two piles: "Correct" or "Not Correct/Not in Time"
- Continue until 3 flash cards are in the "Not Correct/Not in Time" pile
- Using those 3 facts fill in this template
Essentially, the template take those strategies I mentioned above and puts them in a row allowing one to compare and contrast the different strategies. Marzano has long shown that "compare and contrast" is one of the most effective teaching tools.
Of course, the commutative property allows us to think of the same fact in terms of sevens:
I'm not sure if there will be any value in keeping the completed templates and reviewing them in subsequent days. Research shows that simply re-reading the same information is an ineffective way to learn. I suspect the best idea is to keep the completed template for a day or two and then throw it away. It is likely that my son will have to re-do the same fact another day, but that is okay.
- Focus on strategies and number sense NOT on speed
- Focus on REMEMBERING not on memorizing
Am I just being a helicopter parent?
Am I needlessly worrying about this?
Will my plan cause more harm than good?
Tell me what you think on the comment section below.

Q: According to Duane, research shows math homework in K-5 doesn't increase student achievement, why do we use it? Why does Eureka Math have it? Would like to see the research to support this?
Despite decades of research on homework, there is absolutely no consensus on its effectiveness. In general most studies agree that homework is least effective for elementary students. Harris Cooper, a Duke University researcher, found that homework did not correlate to achievement for elementary students, though it did for older students.
While his 2006 study does indeed show a positive relationship between homework and student outcomes at the upper grades (middle school and high school) there was one group in the study for which homework was not correlated with achievement: elementary school students. For these children, the report states that “the average correlation between time spent on homework and achievement … hovered around zero,” or no relationship.
At best, most homework studies show only a correlation, not a causal relationship between homework and achievement. Ironically, Epstein (1988) found that “more time spent doing homework, more help from parents, and more requests for parent involvement from teachers were associated with lower achievement in reading and mathematics.”
Moreover, Swank (1999) examined the differences in test scores among fourth graders who either did or did not do homework. Her findings indicated no differences in math achievement scores between students in the two homework groups.
Lastly, there is evidence that parents - intending to be supportive of their child during homework time - actually increase the level of math anxiety in their child. Essentially, math anxiety is contagious and homework is prime time for transmission.

This is an exciting time to be a mathematics teacher-educator. In the past two decades, we have developed a much better understanding not only of how children learn math, but also of how to teach math – and how to prepare teachers to teach math.
