Activities for Home

Word Builder Spelling

Use the magnet letters or the word builder cards. The students then work with a partner with one calling out the word and the partner making the word. For example, one might call out the first spelling word, frog, and then the other partner would take his or her letters to spell the word frog and then they would write it on a piece of handwriting paper. The two partners would alternate calling out words until both partners had called out and spelled every spelling word.

Gold Spelling

Make a pot of gold out of construction paper and glue to on to a piece of paper and then make little yellow circles (gold) to glue onto the pot. On each circle the students will need to write a spelling word. The students then glue it into the pot.

Shaving Cream/Sand Tray

Using shaving cream as a canvas, the students each get a squirt in front of them to spread around. They can work with partners or the teacher can call out the words and the student must spell it using their index finger. If that wouldn't work, get a tray, fill it with sand, and set it at a center, and the kids can use their fingers to write their words in the sand.

Spelling Mat

 I have a huge spelling mat (Twister game with the alphabet). I have start and finish rectangles. Each letter of the alphabet has its own circle. The kids sit around the mat and one by one they get up to spell a word. They stand on start, say the spelling word, say each letter as they step on it, then step on finish and say the word again. They love to help each other. If they misspell the word, they have to start over again.

Spelling Detective

 You write all of the spelling words on the board and you let the students study them for one minute. After one minute you tell them to put their heads down and you change a word, misspell it, or change the tense, whatever throws them off. You tell the students "Spelling detectives raise your heads and tell me what is wrong." You call on a student and they have to spell the word correctly to you. You change the word back and give the students as a whole a point. If they are wrong, YOU get the point. My group is very loud and can get out of control, so to cheer I tell them to do a silent thumbs up. If they get loud, I take one of their points.

Rainbow Spelling

Use handwriting paper or use lined paper and ask the students to use two lines and then the students use 5 crayons to make the words look like a rainbow. In other words they are writing each word 5 times and they don't even realize it.

 

 

Fishing for Words

On 3"x5" cards print the students spelling words, fold in half, and fasten search with a paper clip. Place the cards in a large fish bowl. Using a toy fishing pole or a long stick, place a magnet on the string. Go fishing for a spelling word to practice.
