Ocean Word Problems

The students used paper fish manipulatives to solve addition and subtraction word problems. Each student could pick their own numbers to use. They then solved the problems. After solving their own problems, they worked with their table groups to  check them.

Balancing Number Sentences

The students used balance scales and manipulatives to demonstrate different ways to make the same sum. This helps them understand two different number sentences that are equal or to find a missing part of a number sentence.








Number Sentence Match Up

Mrs. Timms, who plans our math, came up with a fun game for the students to play to practice finding equivalent number sentences. The students have a set of cards with number sentences on them. They turn two over at a time, like in a traditional matching game. If the number sentences equal the same total, they get to keep the cards. If they do not, they have to put them back. This is a great game for them to play for additional practice while I work with  small groups.






Taking Math Outdoors

After several weeks of freezing temperatures, we have been loving the warmer weather. So, we decided to take math outside. We have been learning about balanced equations or number sentences. The Students took a dry erase board outside and I called out various number sentences. They wrote the number sentences and then drew circles under each addend. They then counted the number of circles on each side of the equal sign to see if both sides were equal, or balanced.



Doubles Snack

To review the concept of using doubles to solve addition and subtraction number situations, the students made edible dominoes. They added icing on top of a graham cracker and then drew a line down the middle with the knife. Then, they added one chocolate chip to each side to represent the pips on a domino. As they did this, they said the related addition and subtraction number sentence. Then, of course, they ate them!

Holly Wreath Fact Families

To quickly review addition and subtraction fact families, the students created Holly Wreaths. They counted how many leaves and how many berries and wrote their corresponding number sentences. You can download the templates for this mini-lesson here.

Shaving Cream Fun

To have a little fun and clean off their desks, we played in shaving cream during the last week of school. The students practiced writing their word wall words, solve addition and subtraction problems, and drew pictures in the shaving cream.

Fact Family Flowers

A former teammate of mine had a great idea to have the students create Fact Family Flowers. Each student was given a set of three numbers that would create a Fact Family. They had to decide what two addition sentences and two subtraction sentences they could create with those numbers. They recorded their numbers on the flower petals. Their flowers were added to the garden display along with their garden research and frog life cycles.

Addition and Subtraction with Bar-Type Graphs

Ms. Willemin taught the students how to use information on a Bar-Type Graph to add and subtract. Using the Promethean Board to display various graphs, she asked them different questions to compare data by adding or subtracting.

Ocean Addition and Subtraction

To review addition and subtraction word problems, the students worked in groups to solve two problems using fish clipart. As they worked, we practiced strategies such as counting up or down, using pictures or manipulatives, or identifying related fact family number sentences.

Large Scale Math Mats

Fellow teachers, if you are looking for a way to incorporate movement and engagement into your math lessons, try creating math mats on the floor with painters tap. Here are some examples of some large scale math mats we use in our class. One is a part-part-whole mat and the other is a ten frame. They are large enough that the students can step in them or we sometimes use manipulatives.




Making Ten Strategy

As we continue to learn our math facts, one strategy that we continually work on is "making ten." The students practice adding and subtracting from ten so that when they encounter a larger math fact they can use their knowledge of "making ten" to quickly add the larger number. To help them get a strong hold of adding and subtracting ten, they worked over a few day period to build numbers to ten with their corresponding number sentences on Ten Frames. Fellow teachers, you can download these forms from my TpT store.



Making Ten: Valentine's Chocolate

To review the concept of adding to ten, the students colored a box of Valentine's chocolate as either dark chocolate or milk chocolate. They then added the two kinds of chocolate together and completed the corresponding word problem. They then compared their number sentences with their partners. Learning the factors of ten helps students when using mental math to add larger numbers. Fellow teachers, you can download this file from my TpT store to add to your files for next Valentine!
