I’ve got a similar worksheet over at the main TJ site for  number words zero – ten in the math section.

## Preschool Math: Number Printables

(numeral that can be traced with the fingers; shows where to start when writing the numeral; word form, and objects) for numbers 1 – 10. Some things we do with these: tracing with our fingers, spelling the number aloud, telling the number of letters in each word name, counting the objects on the card. I’ve also seen activities where the preschooler can use play dough and lay out some dough in the shape of a number on the cards (we laminated them). The cards can also be put in order from least to greatest, greatest to least; they can be used for counting.

– 3 way match, match all three (number/word/objects)

Match two cards at a time or all three for one number.

### Blackline Masters and Assessment Cards for Preschoolers/Kindergarteners

There’s a really nice site with free blackline masters (old term, lol, basically what teachers would make copies from in the “old days”) of preschool manipulatives (such as numeral cards, hundreds charts, place value strips, etc).   I remember using these materials (from this site) in my earlier days of homeschooling.

They also have some helpful PDFS of teaching tips and math activities that you can do with younger students as well as some printable assessment cards to assess what skills your little one has and which ones need to be improved. (I plan on taking those right now as a start for our preschool math routine, insha Allah).

So if you get a chance, stop by and check it out as there are loads of useful goodies here…………Math Their Way Summary Newsletter

## Prime and Composite Numbers; Prime Factorization

We’re studying the above topic and here are some resources I found: (various grades from 3rd – 7th)

Prime and Composite Numbers

Prime Numbers Lesson Plan for Grades 3-4

Am I Prime? Lesson plan  for Grade 7

Prime Numbers Lesson Plan (PDF) for grades 4-6

Prime and Composite Numbers lesson plan for middle school

Prime and Composite Numbers with the use of manipulatives

More than you probably ever want to know about prime numbers here. 🙂 Just thought my son would like the chart.

Prime Factorization and Factorization Trees

Why Learn Prime Factorization? How does it apply to the real world? (humorous and useful for those students who can’t focus on doing something  they don’t know why they are learning it)

Factoring Numbers Lesson from Purple Math

Modeling Prime Factorization Lesson

Prime and Composite Numbers/Prime Factorization  lesson plan from  lessonplanspage.com

I went through my NCDPI  (learnnc.org–NC has some of the best education stuff from state education departments that I have seen on the net) printables (Week by Week Essentials) and pulled out related prime/composite, prime factorization problems for quizzes, practice and warmups:

Prime/Composite Number Warmups/Quiz Material/Practice

What is the only number that is neither primer or composite.

What can be said about the number 1?

What can be said about the number 2?

What can be said about any composite number?

What can be said about any prime number?

Prime Number Dice Roll a pair of dice and add. Is the

sum prime or composite? Suppose you had multiplied, would the product be prime or composite? Suppose you decide to play a game: one person scores a point for each prime number (obtained by either adding or multiplying) and the other person earns a point for each composite number he or she is able to obtain at a turn. Would this be a fair game? Why or

why not? (Note: I use two sets of numeral cards with digits 1-6 instead of dice)

Prime Numbers with the Hundred Board (Blackline

Master I – 76) In these hundred board activities students identify numbers less than 100 with only two factors, one and the number. These, of course, are prime and students can record these as such in their math journals.

There should be 25 numbers in this list of primes less than 100. All other positive numbers, except 1 which is neither prime nor composite, are composite. Ask students to imagine that they don’t have their list of primes and need to decide whether a given number is prime or composite. How might they approach this task? Would square tiles be useful? Would calculators be helpful? Allow students time to discuss this problem.

5 (squared)  x 3 (squared)  is the prime factorization for what number?

What is the largest prime factor of 200?

The digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 are

written on tiles and placed in a bag. Without

looking, Susan draws one tile, records the number,

replaces the tile, draws a second tile and records

that number. What is the probability that she will draw only one

prime number?

Draw a spinner, using numbers less than 20, that satisfies the following conditions:

• the probability of spinning a prime number is 25%

Prime or composite?

## Math Library Guides for grades 2-6

I mentioned these guides in the previous post for sixth grade and up, here are grades 2-5 and grade 6 again……………..

Accelerated Math Library Guides

## Math Roundup

I was surfing for math resources today and for me, I hit the jackpot, so sharing…………………

1. Algebra PowerPoints. This site has loads of Algebra tutorial PowerPoints, they are arranged systematically I guess according to the book that is being used by that particular teacher.

“The matrices are a series of online tables of electronic and technology resources supporting California middle school math content standards for grades 6, 7 and Algebra 1. The resources align to the two California state-adopted middle school textbook series of McDougall-Littell and Prentice Hall. The Grade 6 matrix also aligns to Harcourt and Scott Foresman.”

Basically locate a topic and find online resources to help you teach it or for practice for the student  🙂

Now, as someone who basically put together her own curriculum, this seemed like the best find of the day:
Library guides (Grades 6, 7, Pre Algebra and Algebra) from Accelerated Math (via another site). If you are making your own curriculum, you may find this very helpful. They are pdfs, which have a table of contents of topics, BUT under each topic is an objective, THEN for each objective, it gives sample problems.  So if you are making your own curriculum, you would have an idea of what types of problems to assign and you could look for worksheets or whatnot on the internet.  I thought this was really a find as I do make my own curriculum for most subjects and so often you come across  scope and sequences, which are helpful, but then you have to guess at what kinds of exercises to provide…
the seventh grade one is 152 pages! Haven’t gotten a chance to look at the others…………………..

Here are the links to the individual files:
