Need ideas

I am putting together a unit on addition and subtraction (actually using addition and subtraction to solve meaningful word problems). I have tried many methods before, but I need fresh ideas. Does anyone have great lessons to go with this skill?

Thanks in advance.

This may sound silly but I love the word problem book that uses 'mad libs'. I know this isn't a lesson, but would make a great center idea. Its called 50 Fill In Math Word Problems by scholastic.

maybe focus on vocabulary

Teach them which words mean add and which mean subtract. They should highlight, underline or circle to key word before solving the problem. Some on PT shared this list of key words some time ago. My students found it very helpful.

I don't know if this will help or not, but sometimes I like to focus on different problem solving strategies. I've made some worksheets that require students to use a particular strategy for problem solving.

I do a read aloud before solving

problems by working backwards. It is titled Round Trip and is by Ann Jonas. The picture book can be read forwards and backwards. The drawings are all black and white and create different pictures when turned right side up and then upside down. It is unbelievable art work and the students love it! It really helps demonstrate the idea of thinking and working backwards.

I have found that students do a better job if they have a problem solving procedure to follow. It helps them to really think the problem through. Here is one that we used in the past.

ADD sheets set-up
Old 07-09-2010, 08:40 AM
 
Clip to ScrapBook #13

Have you ever used the TIPS idea from the ADD sheets? (I think ADD stands for Arithmetic Done Daily, or something similar) Our district uses these exercises that were copied 3 per page as morning work or review in math and each exercise has a word problem at the bottom.
We teach the kids to set up all word problems in the TIPS format:
Process: First, read the problem twice, once out loud and once in your mind. Then underline the key word(s) that tell you which operation you think you will use (+,-,x).
Fill out the TIPS outline:
T (Thought) = Operation you will use
I ( Information) = numbers that are given in the problem that are needed to solve it
P (Plan) = write the number sentence (ex.: 34 + 23 = ?)
S (Solution) = write the solution including the unit

This really works for my kids.

Thanks for all the great problem-solving ideas. I especially like the sheet where they have to solve problems using specific strategies.

I'd post these in Word, but for some reason it doesn't attach or print right.

Have you heard of Fosnot units?
Old 07-10-2010, 11:57 AM
 
Clip to ScrapBook #18

They are AMAZING math units! I have used them in first grade and now I'll be teaching third and DEFINITELY plan on implementing them. My students learned to THINK and APPLY amazing problem solving strategies. The units start out with a Big Book or a poster that sets the stage for all of the mathematical thinking of the unit.

The teacher's manual provides an explanation of the mathematical thinking that will be scaffolded in addition to the basic directions of each activity. Easy to implement and one of the most valuable components to my math program. Differentiation is naturally built in.

At the end of the year, my first graders were performing addition with regrouping in the ten thousands and I never taught the algorithm. They used their understanding of place value and numbers to solve. I could go on and on about the BRILLIANT thinking my children developed due to these Fosnot units . . . multiplying two and three digit numbers . . .
