A Rap Retelling of the True Story of Christmas

(3)
This product is a lyrics video. Merry Christmas y'all! (Find this video also on youtube: https://youtu.be/Yer4d8Ugxf4 ). A .docx Word file of the lyrics is also included for your convenience. Feel free to use this in your schools, or perform it yourselves, and distribute it freely! I didn't compose the music or design the picture... I just wrote the lyrics and performed the rap. The Christmas Story (lyrics and rap by Timothy A. Calford, music taken from youtube by soundblue official) "... that baby born on Christmas morning altered history!"

Fractions of the Earth - Collaborative Colouring Math Mosaic

A highly engaging way for your students to practice their fraction operations! Your students will each work independently on their unique worksheet (each is unique!), then combine their work to create the Earth mosaic! Individual accountability is ensured, while collaborative motivation provides a powerful push to complete the work! The end result will look spectacular hanging on your classroom wall! INCLUDED: ◾.pdf file containing all that follow below: ◾ 25-Sheet class set or worksheets that combine to create the large Earth mosaic ◾In this version, each worksheet contains 36 fraction problems. Every sheet is unique! (For a lighter workload, check out the Light Version where each sheet contains only 12 fraction problems, and the worksheet style is a more traditional colour-by-number.) ◾Every worksheet has the answers scrambled at the bottom, allowing students to self-assess their work. ◾Full answer key for all worksheets (both a colour key and calculation answer key) ◾Completed mosaic template with coordinates to help you assemble the completed mosaic ◾Teaching Tips for smooth implementation Students solve the fraction problems, then use the answers to colour their worksheets based on the colour key. Their sheets combine to create the Earth! It's simple! 1. Calculate the answers. 2. Colour the squares. 3. Cut out your section. 4. Combine with the class! The student buy-in factor is HUGE with these worksheets; they all want to see the finished picture come together! Middle school students love colouring too! This sure beats textbook homework! This would also be a good review before teaching rational functions to high school students. Imagine if your students were the ones policing homework completion? "Common Jenny! Do your work or we'll have a hole in our picture!" Leave the picture a secret, or let them know in advance for motivation… it’s your call. Encourage students to check their answers by finding them in the randomized list on their worksheet before they colour each square. This will increase the accuracy of the final picture! All my “Colouring by…” worksheets use standard pencil-crayon colours found in the Crayola 24 pack. For best results, use the exact colour name match (and encourage quality colouring!). Perhaps a class set of pencil crayons would be a fun math department investment! Feedback, suggestions, and frontline stories are always welcomed! Thanks for checking this out! ~CalfordMath

Colouring by Pythagorean Theorem, Malala Yousafzai (30 Worksheet Math Mosaic)

(0)
Collaborative motivation meets individual accountability in a highly engaging task involving Pythagorean Word Problems and Applications. Math + colouring + social justice = something you've never seen before! Each student's worksheet is different! Each worksheet represents a small section of the big picture! The end result will look spectacular hanging up in your classroom :) What a great way to celebrate Women's History Month! **Curriculum Connection** CCSS.Math.Content.8.G.B.7 (Grade 8 Geometry) Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions. CCSS.Math.Content.HSG.SRT.C.8 Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems. (The Malala mosaic is also available in Volume and Surface Area version.) It's simple! 1. Calculate the answers. 2. Colour the squares. 3. Cut out your section. 4. Combine with the class! Students complete the problems to decode the colour-by-number key, then colour their section of the mosaic. INCLUDED: (.pdf ) -Class set of 30 worksheets that combine to create the Malala mosaic -Each sheet contains 12 word problems and applications of the Pythagorean Theorem. -A Teaching Tips page, for smooth implementation -An answer-range key for quick student assessment at a glance. (i.e. "Blue always has an answer between 120 and 160") -A coloured coordinate-labelled image of the mosaic to help you assemble the completed picture. High school kids like colouring too! Their curiosity and desire to see the big picture come together will keep them working and helping each other! All my "Colouring by..." math mosaics use the standard colours found in a Crayola 24 pack of coloured pencils. For best results, use the exact colour name match, and stick to one type of colouring medium. Maybe a class set of pencil crayons would be a fun departmental purchase? :) I'd love to hear from you! Let me know how this went in your classroom! (calfordmath@live.ca)

INCLUDED: (.pdf ) -Class set of 30 worksheets that combine to create the Malala mosaic -Each sheet contains 12 word problems where students solve for Volume and Surface Area of Rectangular Prisms & Pyramids, Cones and Cylinders -A Teaching Tips page, for smooth implementation -An answer-range key for quick student assessment at a glance. (i.e. "Blue always has an answer between 120 and 160") -A coloured coordinate-labelled image of the mosaic to help you assemble the completed picture. -A "Problem Order" list, giving the order of problem types on the worksheets. Here are a few Sample Problems (since the preview doesn't show them): -->The attic of an old house is in the shape of a rectangular pyramid with base dimensions of 4.2 by 16.7 m, with apex height 20.9 m. Find the volume of air in the attic. -->The top of Clarence and Ophelia's sandcastle is shaped like a cone, with a diameter of 7.4 in., and a height of 12 in. What volume of sand did they need to make the castle top? -->An upside-down pylon at Ian's construction site is conical with a circumference of 42.4 mi. and height 8.8 mi. How much rain water can it collect? -->A container of diaper cream for Shendrita's little brother is cylindrical with a circumference of 30.9 km and height 1.5 km. What volume of cream fits in the container? All my "Colouring by..." math mosaics use the standard colours found in a Crayola 24 pack of coloured pencils. For best results, use the exact colour name match, and stick to one type of colouring medium. Maybe a class set of pencil crayons would be a fun departmental purchase? :) Enjoy! (calfordmath@live.ca)
