This zipped file contains a PATTERNS and ALGEBRAIC THINKING POWERPOINT SLIDE SHOW for grades 3-4. The 47 slides are a combination of teaching (lecture style) and interactive slides (fill-ins, multiple choice, matching, unscramble the words, etc.).
The vocabulary and concepts included are patterns, rules, symbols, signs, number expressions, number sentences, variables, open number sentences, equations, inequalities, input-output tables, unit pricing, and map interpretation.
Also included is a Directions Page for using PowerPoint and for using the PEN OPTION of PowerPoint.
The preview file is pages 1-6 of the Slide Show so that you can "Try before you Buy".
Great incorporation of skills linking to common core standards. The review of vocabulary, as well as the opportunity for students to to answer questions (I will use dry erase boards) is solid. My only recommendation is that there is a bit too much animation of pictures and fonts throughout the powerpoint; however, some teachers / classes may really love that and it is easy enough for me to shut a few of the animations off. The educational value of this product is a valuable resource for my classroom.
