Math Educators

I’m preparing to teach division with decimals. Our math program doesn’t have manipulatives for the concrete representation. Suggestions how to have students understand dividing with/without decimals?

What if you used representations of $1? Print out and laminate coins and show that way maybe? Kids love money- heck I like money! 😉🥳

What curriculum do you use? Talk about dividing groups into ____ pieces .5 / .5 is going to be a total of 4 pieces so .25 (although) this is a log easier with fractions... Otherwise you could use partial quotients

.5/.5=1 .5/2=.25

I use tenths and hundredths to divide all by fractions so if kids understand that 10 tenths equals 1 I can divide 1/2 by putting 1/10 on every other side until I get 5-10 on each side which is the decimal point five with 1/4 I put 1/10 in each quarter then another tents in each quarter but I can't go around with four more tenths cuz I only have two so I have to go with 4 sets of five hundredths

once you get halves quarters and thirds you can create 1/9 + 1/6 + 1/8 and 1/12 for Fifth's I keep using my distribution of 1/10 with fractions like seventh I always recommend long division

Re visit parts of a whole, and fractions. Use like a Hershey's bar (with the little squares) or skittles etc. Something they can ultimately break up (after distributing the pieces equally), by an uneven # of people. Have them show strategies (drawing a picture is an example) to solve. If you need to you can use fraction tiles to show division also. I hope this helps!

My boy is just over 1yo. He likes me way more than his mom, excited to see me, upset when I leave, clings more to me when sick or hurt, even knows what to call me but doesn't say mama. Anyone similar?
