Do you lot start the twelvemonth yesteryear didactics well-nigh house value too rounding? It's pretty common.
Lots of teachers inward our teacher Facebook groups accept been struggling amongst didactics rounding strategies. I thought it would live on a swell chance to percentage some of the strategies that I used inward my classroom.
Ditch the Rhymes
Confession time! When I showtime began teaching, I thought it was necessary to accept a rhyme for rounding. I taught my students all the unlike rhymes you lot hear. My go-to rhyme was, "Five or more, heighten the score. Four or less, allow it rest."
I came to a realization several years agone that I was doing a disservice to my students when I taught them rhymes well-nigh rounding. I was didactics steps too my students did non genuinely empathize why they rounded the means they did. Then, when nosotros were produce for to a greater extent than challenging numbers, my students were stumped too did non accept a company publish feel foundation.
Rhymes don't learn publish sense.
Rhymes don't learn publish sense.
Students should live on able to explicate the reasoning too mathematical thinking behind their conclusions. Let's ditch the rhymes! Instead, let's hand students a deeper agreement of publish sense.
Strategies to Teach
Start amongst Place Value
My showtime recommendation is to brand certain that your students tin recognize the tens' place. Even inward third grade, it's yet of import to count yesteryear tens.
The side yesteryear side pace is to learn students to position the tens that a publish is between. They should live on able to say you lot that 43 is betwixt xl too 50. The same strategy should live on used when rounding to other house values every bit well.
Number Lines
After your students accept a company recognition of house value, start using publish lines. I propose using both horizontal too vertical publish lines. Number lines assistance students visualize where the publish volition live on rounded to. I accept my students tape the tens on each end, too the publish halfway betwixt these tens. Next, they volition demand to plot the publish on the publish draw of piece of job inward the right location.
Circle too Underline
Once students are comfortable creating publish lines, accept them purpose the circling too underlining method. Teach your students to underline the digit for the house value that you lot are rounding to, too circle the publish to its right. Now they tin purpose the circled digit to decide which publish to circular to.
For struggling students, or students who demand accommodations, keep a hundreds nautical chart nearby. I propose keeping a few charts laminated, or inward canvass protectors for reuse. Students tin colouring inward amongst a dry-erase mark the publish they are rounding, too thus colouring inward the tens that the publish is between.
Other students may simply demand you lot to relate rounding to a existent life story. I've told my students that the hallway represents our publish line. There is a bath on each halt of the hallway. As they are walking downward that hallway, they of a abrupt realize they demand to purpose the restroom! Well, if you lot are non one-half means downward the hall, would you lot decease along going? Or, would it live on wiser to plough some too become to the closer bathroom?! If you lot are half-way or to a greater extent than downward the hallway, it wouldn't live on smart to plough around. Keep going until you lot achieve the halt because it is closer. Sometimes, they simply demand to relate math to their every solar daytime lives.
