Resource #5 - Additional Materials to Print and Practice with Answer Keys:

• Record and Practice Journal - These exercises are written to match the kind of material in the textbook that directly practices skills and problem solving, or that directly applies the standards of the lesson. Exercises occur in the same order in which topics are taught in the textbook, beginning with skill and ending with problem solving.

• Practice A - These exercises provide more additional practice on the key concepts taught in the lesson with more emphasis put on the problem solving portion of the individual lesson. Exercises occur in the same order in which topics are taught in the textbook, beginning with skill and ending with problem solving.

• Puzzle Time - These exercises provide additional practice in a fun format in which students use their mathematical knowledge to solve a riddle. This format allows students to self-check their work.

• Answer Keys - These PDFs show just the answers, not the solutions, but offer the opportunity to see at least if the completed work is correct or not.

Resource #6 - Big Ideas Math Support Videos and Tutorials:

These are one-to-three minutes in length and provide video and audio support for each and every example covered in the class textbook as well as our class notes. Often, these videos complete the same example as we do, just using different numbers so conceptual carry-over can occur. These are valuable for students who miss a class, need a second explanation, or assistance with Daily Practice Exercises.
