Problem 1: Don’t scroll down for the answer yet on how to solve this. Try to figure out the correct answer.
Problem 1 solution: Get one of the values to 10 and then add the remaining number to get the total. So for example, you would say, “I have 8 here and 6 here. To get the 8 to 10 I would add 2. That means I have to subtract 2 from the 6 so it’s 4. So I have 10 and 4 which add to 14.”
Very intuitive, no? Try another.
Problem 2: Don’t scroll down for the answer.
I told you not to scroll down for the answer. Welcome to constructivist math.
Memorizing basic facts is evil and too tedious for children. This will no doubt build a deeper understanding as children struggle to understand math.
Dr. Gary Thompson and Ed Flint should have no problem supporting themselves in the future.
Why do kids need to “get a ten” to do math??? To help kids with their homework we, as parents, will have to sit in class with them to learn it! This is ridiculous.
I taught this concept last year in first grade. It is very confusing for many children! The reasoning behind it is to get them to see groups of 10. The world functions on base 10 and when they finally get it, it does make adding easier. BUT it isn’t developmentally appropriate for a 6-7 year old! They work with two sided counters to do the work in class. The dark ones are red and the light ones are yellow. First graders should be manipulating their way through math to understand concepts taught. But moving from manipulation to such abstract “paper work” is so wrong! Multiple choice answers are so hard to chose from! And the poor parents who try to decipher this stuff when the child brings homework home…without the manipulatives! I’m sorry that ANY school district thinks this is appropriate material. Our district adopted this math without even piloting it!….district wide! And who suffers? The children! The teacher! AND the parents!
District wide without even piloting it… Sounds like Alpine School District’s grand fail when they experimented with Investigations math… I know you’re not in ASD either. This is a state fail. I put the blame at least half on the state office of education, and then half on your district school board members for being uninvolved and listening to “experts” at the USOE and in the district tell them they’ve studied the issue and determined this was best. It never changes…
We memorized adding and subtracting each number 0-10 and it has made a world of difference in my life in adding/subtracting all sizes of numbers. I can add/subtract numbers faster than most people I know. This is a JOKE…
