Five pages on the two signs, with sums and differences within 20. Page 1 starts with what each sign means, then shows two cube trains in each row: same length, write =; not the same, write ≠. Page 2 has twelve pairs to find the value of each side and write the sign. On page 3 students circle True or False for sentences that use both signs, then fix each false one by writing it again with the other sign. Page 4 sorts eight cards under = 12 and ≠ 12, then = 15 and ≠ 15. Page 5 is six short stories that compare two children's amounts.
Build two cube trains, like 4 and 3 and 5 and 2, and stand them side by side: the same length, so 4 + 3 = 5 + 2. Swap one train for 6 and 3: not the same, so 4 + 3 ≠ 6 + 3. Show how ≠ is an equal sign with a line through it, and let pairs make trains for each other to judge.
Make two piles of small things, like 6 and 2 buttons and 5 and 4 buttons. Ask your child to count each side and say "equal" or "not equal", then write the sentence with = or ≠.

A 5-page 2nd grade pack on the equal sign and the not equal sign (≠) within 20. Compare cube trains and write = or ≠, find the value of each side and write the sign in a circle, circle True or False for sentences with = and ≠ and fix the false ones by changing the sign, sort expressions under = 12 and ≠ 12, then compare amounts in six short stories. Every page comes in color and in black and white. Answer keys included.
