Mental Math Article by Kimberly Wesley https://padlet.com/kpwesley237/rwvt5efe725r5h1r en-us 2023-02-20 13:56:15 UTC 2025-12-12 06:19:00 UTC hello@padlet.com Jada- "Constant difference" is what stood out to me because normally in subtraction, you see numbers being taken away from other numbers but this type of subtraction can be shown using larger and smaller numbers but you will still get the same value. Ex. (52-19) and (53-20) both will equal 33. https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491830294 2023-02-22 23:39:49 UTC https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491830294 Using terms like "borrowing" - Kyla https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491832908 Using the term "borrowing" in subtraction doesn't share what is actually happening in the subtraction problem. This stood out to me because I grew up calling it borrowing but it actually doesn't make since because we aren't lending things expecting to receive something back later. But instead using the phrases, "decompse" and "recompose". 
For an example, " Understanding how numbers are decomposed and recomposed can help us make sense of subtraction when we consider 52-19 as being 52-10-9 or 52-20+1 or (40-10)+(12-9) or 49-19+3 (or many other possibilities)…".]]> 2023-02-22 23:44:01 UTC https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491832908 Recomposing/ Decomposing I think it is very important to understand how to decompose/recompose in math problems to show our students that there is more than one way to solve a math problem this is also very important for students that Struggle in math especially if the numbers are too big for them to solve without breaking it down. For example, the number 10 can be thought of as 2 groups of 5, or 5 groups of 2, or a 7 and a 3, or two-and-one-half and seven-and-one-half- Laila B. https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491833902 2023-02-22 23:45:29 UTC https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491833902 Decomposing and Recomposing -Olivia https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491836090 The concept of decomposing and recomposing implies that in order to build a child's skills and knowledge on a subject breaking down a new concept will help support the new learner. The article wrote, "Understanding how numbers are decomposed and recomposed can help us make sense of subtraction." For example, a good representation of decomposing and recomposing would be considering 30-15 as being 30-10-5 per say which would break the numbers down into smaller numbers in order to develop a better understanding of the problem or simplify it. ]]> 2023-02-22 23:49:06 UTC https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491836090 Decomposing and Recomposing -zahra https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491838620 The article emphasized the importance of visualizing the math. Visualizing allows to use manipulatives to see the strategy. It allows us to have a foundation and know we can break the numbers down. For example, 52-19 can be decomposed to 52-10-9. Borrowing is discouraged because we're not hoping to get a return but to be able to break down these numbers so instead we use "decomposed" and "recomposed". ]]> 2023-02-22 23:53:23 UTC https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491838620 Shaqusha https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2491839290 Math can be broken down in various ways and then reconstituted again. The concept of decomposing and Recomposing can make subtraction and addition easier to solve for many because it is the process of putting the number in a form that may be visually more pleasing, and then recomposing the equation to help solve the problem. Visuals can be potentially helpful to students but should be used effectively. If they are used correctly the students should visually be able to see what strategies are being taught and why they work for decomposing and recomposing.

In the article it mentions borrowing and take away. I guess it doesn't make sense when you think of the word "borrow" but teaching children a lot of the ways we were taught math was memory. if you had a game or chant or something that rhymed then it was easy to remember. for example, "borrow from your neighbor" but you aren't exchanging anything in return so I could understand the difficulty in that]]> 2023-04-25 15:45:24 UTC https://padlet.com/kpwesley237/rwvt5efe725r5h1r/wish/2567459039
