SkatingMom Posted June 15, 2014 Share Posted June 15, 2014 We are going with Math Mammoth next year. Are the Answer Keys necessary for grades 1 and 2? Quote Link to comment Share on other sites More sharing options...

Farrar Posted June 15, 2014 Share Posted June 15, 2014 No. If you're buying the printed ones, definitely don't bother. I think they just come with the pdf's though. Quote Link to comment Share on other sites More sharing options...
IsabelC Posted June 15, 2014 Share Posted June 15, 2014 Yes, they come as part of the pdfs. I haven't used them, though, as for the early books it's quicker to check the answers mentally than to look them up. Quote Link to comment Share on other sites More sharing options...
SkatingMom Posted June 15, 2014 Author Share Posted June 15, 2014 Thanks! If I get a new printer I will be getting the PDFs but if not I am just going to get the printed books. My old inkjet goes through cartridges every 200 or so pages at $45 a pop. Quote Link to comment Share on other sites More sharing options...
Farrar Posted June 15, 2014 Share Posted June 15, 2014 I saw someone work out the cost at some point. If you don't have a good laser printer, it may be cheaper to get the preprinted ones (without the answer keys) if you only have one child.

PagesandFields Posted June 15, 2014 Share Posted June 15, 2014 Thanks! If I get a new printer I will be getting the PDFs but if not I am just going to get the printed books. My old inkjet goes through cartridges every 200 or so pages at $45 a pop. I just found out recently I can get generic refilled ink on ebay for about 1/10th the cost for my ancient inkjet... They work just as well... I dream of a good laser printer. Quote Link to comment Share on other sites More sharing options...
LEK Posted June 16, 2014 Share Posted June 16, 2014 No, we have gone through all of 1a-2b and never used the answers yet Quote Link to comment Share on other sites More sharing options...
Forgiven Posted June 16, 2014 Share Posted June 16, 2014 I haven't used answer keys for any of the grades so far, but we haven't done grade 6 yet. Even for 5A and 5B, I think it would've taken more time to look the answers up than to just do the problems in my head. Quote Link to comment Share on other sites More sharing options...
maize Posted June 16, 2014 Share Posted June 16, 2014 I haven't used answer keys for any of the grades so far, but we haven't done grade 6 yet. Even for 5A and 5B, I think it would've taken more time to look the answers up than to just do the problems in my head. Same here. We are in 6a and have not felt the need for an answer key yet. To be honest I only spot check dd's work as she usually has little trouble with math and the explanation and examples in MM are very clear.

boscopup Posted June 16, 2014 Share Posted June 16, 2014 Brother 2270DW laser printer can often be found on sale for anywhere from $60-80. Paper is often free after rebate from Staples and other office supply stores. And MM PDFs go on sale a couple times a year for less than $70. So use those figures when calculating cost. I think a laser printer is a good investment, and they don't have to be expensive. Quote Link to comment Share on other sites More sharing options...
heather124 Posted June 16, 2014 Share Posted June 16, 2014 We have an awesome laser printer, however, for math mammoth, I had Office Depot print them when they would offer a 25% off coupon in the paper. It worked out to be about $20 printing double sided for each section (ie 4a, 4b) for 2 boys. So for about $10 to not have my printer and ink and they 3hole punched it for me, it was perfect! Just an idea.... Quote Link to comment Share on other sites More sharing options...
