Superhero themed Variables and Open Sentences Task Cards provide for differentiation by offering several levels of difficulty. Cards can be used with the whole class, small groups or individual students. Printing on cardstock and laminating the cards ensures that they can be used multiple times.
Cards 1-4 ask students to identify the variable
Cards 5-12 ask students to match a word problem to the number sentence that could be used to solve it.
Cards 13-34 ask students to solve for the variable
Cards 36-40 ask students which of four word problems match the number sentence
