Lesson Planet has helped me give some great extending activities that I hadn't thought of before. It has also helped me be able to deliver a quality lesson when life gets busy, when I'm forced to be on the fly and not as prepared as I'd like to be.

They identify some examples of shapes that represent odd numbers and some that represent even numbers. Students work in groups to find patterns when they add or subtract the numbers the shapes represent.
Explore operations with whole numbers, using a calculator to develop understanding of the effect an operation has on the numbers involved. Your class collects data, looks for patterns, and makes conjectures regarding numbers or operations.
If your second-graders are learning about place value and number value comparisons, this set of engaging activities and worksheets will make your job easy! Scholars use math manipulatives to estimate and then determine how many seeds a colony of Harvester Ants have gathered. They estimate the total number of sticks in a container, grouping them in 100s, 10s, and 1s to make counting faster. Learners also play math games during which they analyze three-digit numbers to 999. These six activities have students competing, moving, thinking, and having fun. Every print-out you will need is included.
Using unifix cubes, a spinner, a number line, and fact family triangles second graders will play their way to subtraction competency. They engage in a series of activities that has them playing game that require them to add and subtract single and simple double-digit numbers. They use flash cards, manipultives, fact families, and a number line to show what they know. Several game boards and worksheets are included.
In this number and operations worksheet, students solve and complete 3 different sections of one problem that uses the Pythagorean theorem to solve. They use the model illustrated to determine the meaning of the Pythagorean theorem. Then, students color each portion the color specified in the directions.
Working with decimals or money math? Give your class some practice with subtraction and place value. After solving 18 subtraction problems with decimals and money units, fourth graders work on two word problems. A great homework assignment or quiz after your math lesson.
What's in the bag? By placing digiblocks into an opaque bag or container, your young mathateticians will have a sense of excitement as they reach in to grab a handful. The activity continues as they arrange their blocks into a representation of the number they symbolize on a place value mat. After recording the value, they create two other representations of the same amount. This is a fun activity which would also work well in pairs! Gradually increase difficulty by allowing two handfuls.
Introduce multiplication with large numbers to your fourth grade class. A straightforward worksheet provides three and four-digit numbers, multiplied by one-digit numbers, to help transition your learners into more difficult multiplication problems. Use this resource as a homework assignment to reinforce your multiplication lesson.
Practice place value by visualizing 10s and 1s. First graders count the cubes in each place, then write the total number at the bottom. In one particularly helpful section, they draw the cubes that will add up to a given number. Bring in blocks for extra practice with place value.
Practice putting decimals in order. This resource presents ten sets of decimals for kids to order. After working through the first five sets, they review measurement and unit conversion (kilometers and meters) in the next five problems. A nice way to review a lesson on decimals!
