Please see the preview for zoomed in images. Math CCS 3.OA.5, 4.OA.B.4, 6.NS.B3, and 6.NS.B4. Factors, multiples, multiplication. Color-coded resource and worksheets. 4-10 days of lesson worksheets to use a consistent review reference and example to use to create similar sheets and assessments. Answer key not needed.
I proudly present a useful set of visual aids and worksheets I created to help third, fourth, fifth, and sixth graders master factors, multiples, and multiplication. I have sold thousands of hard copies of handouts and posters in the USA and Canada through mathincolor.com. I am finally offering a digital version through teacherspayteachers.com after receiving requests from around the world. These work well under an "Elmo" projector or as a hard copy for student reference.
Multiples in Color is a visual aid that puts the multiples of 2 to 10 in a color code on 9 different 1 to 100 charts. Children can use this as a reference and as a way to practice skip counting and multiplication.
Color-Coded Numbers 1 to 100 is a great visual aid for showing how a number can have several or few factors. Each number is assigned a color with the number inside it from 2 to 10. Each number from 1 to 100 shows which numbers from 2 to 10 it has as factors. For example: 24 is a multiple of 2, 3, 4, 6, and 8 so it has color bars with the appropriate numbers inside the bars. 23 is a prime number so it is identified as one without having any color bars.
Color-Coded Numbers 101 to 200 continues the concept displayed on Color-Coded Numbers 1 to 100 and also includes identification for numbers that are not prime but use factors beyond 2 to 10. For example, 143 has 11 x 13 underneath it to show that 143 is a composite number with factors greater than 10.
Multiplication in Color is a color coded multiplication chart that visually shows the factors multiplied together inside the rectangle on the chart to produce a product. For example: 3 x 7 shows a blue 3 multiplied by a brown 7 inside the product box. This helps children focus on the desired part of the chart without getting "lost".
The four prime and composite worksheets display every number from 1 to 100, the factor pairs that produce that number, whether that number is prime or composite and the individual factors for a specific number. For example
18. 18=___x1 or ___x 2 or ___x3. 18 is a _____________number. Factors of 18 are ___,___,___,___, ___and ___.
The child thinks through the number and eventually writes 18= 18 x 1 or 9 x 2 or 6 x 3. 18 is a composite number. Factors of 18 are 1, 2, 3, 6, 9, and 18. This gives children a reference as they work on mastering factors and multiples throughout the year.
All 4 visual aids and worksheets can be used for "self-study" during quiet time or during math time as a learning aid.
I use these products in my fourth grade class and many other teachers in my school and district use it. Kids like it. My high needs urban school had the highest fourth grade 2013 Math MEAP (Michigan's Standardized Test) test scores for the school district and my class went from 6 kids being proficient on the AIMS-WEB CAP test to 14. The 8 highest scores at my school in the fourth grade out of 77 kids were in my class. This is a practical and effective product kids use throughout the year.
I suggest completing these worksheets over 4 days in 45 to 60 minute sessions. This gives you 4 days of lesson plans and a great reference for consistent review.
If you decide to share this with your colleagues, please pay the reasonable licensing fee. It literally took me over 100 hours and thousands of dollars to bring this resource to fruition. Thanks!
