  1. This week we've done some review each day of strategies to do multiplication if you forget a fact, a page a day from MM placement tests, and then some puzzles in BA 3. She's adoring the puzzle book.
  2. So do you think these could be read each in two weeks or so? It looks like I can get them via interlibrary loan, but that would mean we'd have to finish them quickly. Thanks! I'll check these out!
  3. I'm looking for books that are relatively short (can be read in 1-2 weeks during school time) that give broad overviews of ancient cultures like China, Rome, Egypt, Persia, and Greece. I'm going to have kids in each stage (grammar, logic, rhetoric), so any grade level is fine. My library has some books, but many of them look like the ghost written, not engaging style of non-fiction book that is all too common.
  4. Let's leave division off for now and just stick with the other three operations.
  5. I think she'd like these. Maybe a multiplication one, since she needs to work on that. Thanks!
  6. What funny is if I wrote the problem down, stacked, she would not be doing it the way she is with manipulatives/pictures. Then she does the standard way with regrouping to get 13-hundreds. It only seems to be with manipulatives that she resorts to her ten facts to do it.
  7. She's starting to get sick of me asking her to do math during spring break 🤣 So I asked her 2300-700, and I drew pictures of manipulatives. She crossed out one of the thousand cubes and said to herself, "what does 7 need to get to 10?" and then gave me the answer of 1,600. I asked her how she would find 3x7 and she said (with an eye roll), "You skip count."
  8. We have thousand cubes. Do you want me to have her use manipulatives again?
  9. For 83-17 with manipulatives: She took out eight 10-rods and 3 units and set them in a pile. Then she took out one 10-rod and seven units and put them in a second pile. She then took one 10-rod from the 83 pile and said, "minus 10" and took another 10-rod from the now 73 pile said, "it goes 'eh'" and mimicked it breaking as she replaced it with 3 units. I asked her what she had, she put all the units together and counted her tens: "66." For 100-1 with manipulatives: She took a hundred flat. She took a unit cube and set it in one corner of the hundred flat, "You have this?" I asked,
  10. I'll have to ask her tomorrow. I can tell you how she handles simpler stuff without manipulatives. 45+26 would be 40+20=60 and 5+6=11 then 60+11=71 For something like 63-7 she first splits the 7 into 3 and 4 and then does 63-3=60 then 60-4=56 (mentally breaking one 10 to do that).
  11. We're currently using Beast Academy. She seems pretty confident doing it with addition, maybe a little less with subtraction.
  12. I think I'm going to give her some of the math mammoth placement tests and maybe have her work through some of the dark blue series books. They don't have grade level, so she may not notice that it's working on lower level stuff. And if she is given math puzzles, that would tickle her. I think I want to focus on place value first--would it be possible to make crosswords that cover that somehow? Would it be possible to use with cuisinare rods and base ten blocks? It'd be a lot cheaper if I didn't have to buy the manipulatives!
  13. So how do I go about remediating? Or even finding out where all the gaps are? I can't start her over in grade 1 math just to make sure she covers everything she needs.
  14. It could possibly work. She would love if I got one of the puzzle books for her. She's done OK with MM the times we've used it. When we use BA, she enjoys math, even if it's hard and not always understandable. When we do MM, she doesn't enjoy it as much, but she does seem to get it (fewer conceptual leaps, I think). I wish there was a math that would be both enjoyable and understandable for her. It's possible. We don't really do tests in elementary, so she's not used to them. But she has no idea what the standardized test is about or anything like that, so she wouldn't be worried a
  15. For the 8x6 problem, she says, "It means 8 groups of size 6" For the fraction problem, there was lots of conversation. I tried my best to record it. Me: (writes 22/5) What does this mean? Her: Five pieces of 22 pieces? Me: So you know it means pieces--how big are the pieces? Her: (just reading the fraction) Twenty-two fifths Me: What situation would we use this number for? Her: Cutting pizza, cake, or pie Me: How many pieces of cake do we have Her: 22 Me: How many pieces does it take to make one cake? Her: one cake would take 5 pieces Me: Where on the number line would 22/5 be? Her: (blan
  16. As an example of problems she couldn't do on her standardized test: 8x6, 36÷6, and other simple, rote 3rd grade math topics. Even though we've spent all year doing activities to get understanding of multiplication and division and how they relate. We have spent a lot of time on models of multiplication and strategies to get the answer if you blank out and forget a math fact. She instead spent 10 minutes scribbling out 8x6. She didn't even try repeated addition or skip counting to get it. If it weren't a test, I could have suggested it and she would have gotten it, but it didn't come to her on
  17. We do lots of different things. We're mostly using Beast Academy, but I spend time playing math games with her several days a week to work on math facts and we use different math manipulatives and do mini lessons aside from her book when she's stuck. I have lots of resources to pull from, and I try to do so when it seems like a concept isn't making sense. But apparently it hasn't helped. The most recent topic we did that seemed to confuse her was switching between a fraction greater than 1 and a mixed number. So if she had 22/5, she wouldn't be able to get that to 4 and 2/5 wit
  18. My youngest does not find math to come easy. She can do it, but it always seems like she doesn't quite fully understand. And, with six weeks left of 3rd grade, she bombed the math portion of standardized testing. It's as if she didn't learn a single thing I taught her over the last year. We use a test where you can compare previous year's scores to see progress, and she literally had no progress in math. So. What do I do? I obviously can't move on. And I'm wondering if I need to go all the way back and have her redo basics like place value before having her redo 3rd grade math again. My
  19. I was just recently disappointed by the lack of good apps for high school math. My son will be doing pre-calc this next school year and I'd love for there to be an actually useful app.
  20. I have seen that, and we're going slowly. But the long lessons and slow progress are discouraging. I chose it for the content it teaches, but it just isn't a good fit for my family.
  21. My kids are ready for the depth of grammar in Grammar for the WTM, but the lessons are so very long. We've been breaking them up, but now it will take us (what feels like) 20 years to get through the book. Is there anything available for grammar that goes to a similar depth/difficulty but has shorter lessons? I'm hoping for something that is 1-2 years max because we've already wasted so much time very slowly moving through Grammar for the WTM.
  22. I need a workbook spelling program for my son. It looks like most middle school spelling programs transition to vocabulary, but he still needs spelling practice. He's refusing to do sequential spelling with me anymore, so we need something that is independent. thanks!
  23. I've seen the recommendations that the first half of intro to algebra is alg 1 and the second half is alg 2. Comparing the topics to what I remember having learned and what the local high school lists for alg 1 and alg 2, it didn't seem to fit. Most notably polynomial division, more in-depth coverage of logarithms, and conic functions. Thanks for the mention that there are alg 2 topics in in the intermediate algebra book (assuring me that I'm not crazy). He's did the whole geometry book, so he has done the brief section on trig functions. He does like programming, and so I've deba
  24. I forget the exact details, but Prodigy placed my child multiple grade levels above where she was actually working. During the placement test, it would give her only a few questions per grade level before "advancing" her (eventually incorrectly).
  25. My son is getting bored with the heavy focus of polynomials in AoPS Intermediate Algebra (we're about to finish chapter eight). It's been ages since I took algebra 2, but would it be any different with a different text? Or is this just a huge part of the course regardless of the source? If I were to give him a short break from the book, what topics would be good as a distraction from polynomials?
