With Thinking Tools

Activity 1: Introduction to variables; add things like apples and animals; may you add or not; why; then it’s about the addition of letters presented as pictures; conclusions; brace map

Activity 2: The same principles as Activity 1, but for subtraction

Activity 3: Define term, like and unlike; brace map

Activity 4: Addition; like or unlike; pictures; write the problem and answer; step-by-step

Activity 5: The same principles as Activity 4, but pictures of letters; addition of binomials to expressions with four terms

Activity 6: Conclude that 1 letter is the same as a letter without 1 in front of it; pictures of letters; tables; abstract binomials; like or unlike; give answer; expressions with four terms – 2 with one variable and 2 with another variable; add

Activity 7: Addition; abstract; binomials to expressions with four terms

Activity 8: Menu; use it to substitute words with variables, substitution and work out totals; word problems; step-by-step

Activity 9: Define the word pair; two times 0, 1, 2, etc. with pictures of the same amount of peas in pair of hands; conclude what bracket means; conclude definition of variable and constant; brace map; identify variables and constants; table

Activity 10: Subtraction; like or unlike; pictures; write the problem and answer; step-by-step

Activity 11: The same principles as Activity 10, but pictures of letters; binomials to expressions with four terms

Activity 12: Conclude that 0 of a variables is 0; subtraction; tables; abstract binomials; like or unlike; give answer; expressions with four terms – 2 with one variable and 2 with another variable

Activity 13: Subtraction; abstract; binomials to expressions with four terms

Activity 14-15: Geometric patterns; give first 3 patterns; give variables for pattern number and answer; complete table; find difference; work forward in flow map; questions; write formula; complete table with larger pattern numbers; define input value and output value; identify input and output value; work backwards in flow map; backwards formula; describe what you did, in words

Activity 16: Look at values in tables of four patterns; conclude where the coefficient comes from; conclude how you know which number to add or subtract; write formulae

Activity 17: Geometric patterns without constant difference; complete tables; describe the pattern in words
