1st Grade Math Scope/Sequence 3rd Six Weeks Burleson ISD (1.5) Patterns, relationships, and algebraic thinking.   The student recognizes patterns in numbers and operations.       (C) identify patterns in related addition and subtraction sentences (fact families for sums to 18) such as 2+3=5, 3+2=5, 5-2= 3, and 5-3=2.      http://www.aaamath.com/B/g210a_x1.htm Explores the relationship between subtraction and addition and provides practice with immediate feedback. http://www.lovetolearnplace.com/Curriculum/Math/addition/Math%20Families.html         This site may be used with the projector to discuss fact families. It also has suggested activities, problems, and experiments to do at home. http://www.dositey.com/addsub/addbasicml.htm Addition demonstration and on-line mini-lesson http://www.dositey.com/addsub/sub1dig.html Subtracion demonstration and on-line mini-lesson http://illuminations.nctm.org/lessonplans/prek-2/connect_cubes/index.html#l5 Lesson on fact families from NCTM http://illuminations.nctm.org/lessonplans/prek-2/dominoes/index.html#l6 NCTM lesson on Finding Fact Families http://illuminations.nctm.org/lessonplans/prek-2/fish/lesson5.html NCTM lesson on Fact Families http://illuminations.nctm.org/lessonplans/prek-2/lets_learn_facts/lesson1.html The communitive property from NCTM
