Place Value in Kindergarten

     Last week, my kindergarteners started working on numbers and operations in base 10. Success, success, success! This standard is being mastered. Here is what we have been doing!

     We begin every math class with a GoNoodle brain break followed by an engaging math video. Harry Kindergarten Music has two GREAT videos/songs for teaching the teens to kindergarteners. Numbers in the Teens (They Start with a One) helps with number recognition for numbers 11-19 and Number in the Teens (Have a Group of Ten) is good for helping students understand that numbers 10-19 are composed of ten ones and some extra ones. I added these to my GoNoodle account for easy access.

     After the video, we use our base ten blocks or our ten frames and counters to practice counting. First we count using real number names, "ten, eleven, twelve, thirteen..." Each time I remind them that great mathmaticians do not waste time counting by ones when they can already see that they have ten. After we count using real number names we count the say ten way, "ten, ten one, ten two, ten three, ten four..." I remind the class that ten and one more is eleven so ten one is just another way to say eleven. I would not recommend counting the say ten way if your students have not mastered counting to twenty or have not yet been exposed to teen family numbers.

    We are working on creating these adorable ten frame books in class. Next week, we will create a similar book that uses base ten blocks to demonstrate composing numbers 11-19.

Math Center Activities for Base Ten for numbers 11-19 

Dry Erase Strips 

The books we will make next week will match these dry erase strips! 

Ten Frame Number Puzzles

This activity also includes ordering numbers 10-19. 

Number Mats 

       Grabbed the perfect sized toy cars for these mats from the Dollar Tree! Students also use dry erase markers to practice tracing the numbers! 

It's not too early for Valentine's Day activities, right?

Valentine's Day Math Centers and a FREEBIE!

We've been working hard to master those common core addition standards so we are practicing them with our Valentine's Day math centers. Here's what we have going on this week!

CCSS.Math.Content.K.OA.A.3 Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).

I got this idea from Fairy Dust Teaching Blog's post: Addition Made Easy. I first taught this lesson in whole group. We did Ways to Make Seven using cards and paper clips. (See the step by step instructions from FairyDust.) It definitely worked like magic and every single one of my kinders was successful! Praise the Lord! They had a great time with it too. I found the adorable little heart clothes pins on the dollar isle at Target.

CCSS.Math.Content.K.NBT.A.1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.

     This particular standard has been a real doozie for my babies, but I think we are finally getting the hang of it! I love the look on this girl's face! You can tell she is proud of her work, can't you? In this center students simply model the addition fact using Sweethearts candy! I gave my students their own labeled candy bags. The students knew ahead of time that I would give candy to eat if they could return these bags with ALL the candy hearts still inside. If candy won't work for your students you can always use heart shaped erasers, pompoms, or even dry erase markers! Just visit my TPT store for these great Valentine's Day Playdoh and Counting Mats #1-19.   If your babies have struggled with this standard too you may also want to check out my Number Sense and Operations Math Pack!
