The Water Cycle

 

The Water Cycle

Enjoy learning about the water cycle for kids. Understand how the water cycle works with our facts that help explain the different processes in a way that’s easy to follow.

Follow the diagram and learn about evaporation, condensation, precipitation and more.

Evaporation:

Heat from the Sun causes water on Earth (in oceans, lakes etc) to evaporate (turn from liquid into gas) and rise into the sky. This water vapor collects in the sky in the form of  clouds.

Condensation:

As water vapor in the clouds cools down it becomes water again, this process is called condensation.

Precipitation:

Water falls from the sky in the form of rain, snow, hail, or sleet, this process is called precipitation.

Collection:

Oceans and lakes collect water that has fallen. Water evaporates into the sky again and the cycle continues.

Extra:

Transpiration:

In a process similar to sweating, plants lose water which is absorbed into the atmosphere much like evaporation. The combination of evaporation and transpiration is known as evapotranspiration.

Sublimation:

It is possible for a solid to transform into a gas directly (without becoming a liquid). The most common example of sublimation is dry ice (solid carbon dioxide) which sublimes at normal air temperature. Under certain conditions snow and ice can also sublime.

Effective Ways to Teach Addition in Kindergarten

Effective Ways to Teach Addition in Kindergarten

 kindergarten students usually require a variety of hands-on and engaging activities. Teaching addition in kindergarten is no exception! In order to effectively teach this concept, students need to understand what it means to add before they’re asked to start completing worksheets and writing number sentences.

Here are some of my favorite's ways to teach addition to young learners. Incorporating some of these activities into your addition lesson plans can bring some extra engagement to your math instruction.

1. Teach (and Display) a Variety of Addition Strategies

The first step in teaching addition to kindergartners is to show them a variety of strategies. These strategies will help your young learners understand the concept of addition. Your students will be able to find and use the strategies that make the most sense to them! 

One of the best ways to teach these addition strategies to your students is with strategy posters. As you introduce each strategy during math instruction, you can hang up a corresponding poster in your classroom. Over time, you will create a useful display of addition strategies. Then students can refer back to the strategies whenever they need to!

A bulletin board full of addition strategies can serve as a helpful anchor chart! These strategies will help your students become more independent as they solve addition equations during independent work time, small groups, or centers.

2. Practice with Addition Task Cards

Once you have taken the time to teach addition strategies, it’s time to put them into practice! Simply laminate the center cards, hole-punch the corners, and add a binder ring. During centers, students can grab a group of addition task cards and then get to work!

I like to group the task cards by strategy so that students can practice the different strategies as they solve simple addition problems. I include a cover sheet on each bundle of addition task cards so students can see which strategy they will use.

3. Use Addition Songs

Kindergartners love music and singing is an excellent way to practice addition!

Fun addition songs give them a chance to get up and move after sitting in their seats all day. Whichever song you decide to use, be sure to encourage them to stand up and move in some way.

There are plenty of others but these are always a hit with students! Jack Hartmann always has my whole class singing and dancing. The songs are easy to memorize, so kids find themselves singing the songs while solving problems.

4. Play Addition Games

Learning how to add takes practice and plenty of repetition. In order to keep your young students engaged in the repetition needed to master addition, try playing some games!

Students love to roll the dice, add the numbers together, and then cover the correct answer on the mat. This simple game is so fun for students that they’ll want to play again and again. Since the rules of this game are simple, it’s the perfect activity to add to your math center rotations

5. Introduce Addition Story Problems

One of the most important parts of teaching addition to kindergarten students is how it relates to the world around them. You want to show your students that addition is more than completing a number sentence on a math worksheet.  A great way to help students recognize math in a relatable situation and then model it with a number sentence.

This will make addition more meaningful to your students, and they will be more likely to understand and remember the addition strategies they are being taught. Finding relevant information in a story problem is a skill that students will use for years to come.
