Use of Technology: Numbers & Operations in Base Ten
Use of Technology: Numbers & Operations in Base Ten
With the use of online virtual learning and the constant need to differentiate instruction for students, I felt it was vital for me to explore the many online resources that would aid in teaching third grade mathematics.
Addition
Found on the NCTM website, this ten frame interactive is beneficial as it plays to students spatial awareness. This website uses a base ten model to show addition in relationship to ten.
Students here add different amount of chips to each of the ten frames, then you must combine the ten frames. In this last picture, you can easily see that the first ten frame is full and there are two more chips in the bottom ten frame. Students at this point can see that it is ten plus two, or twelve.
Multiplication
This tool will be able to assist students who are visual learners. Students can plug multiplication problems in to the website and it will generate a box showing the product.
Place Value
I am not a fan of have students just solve problems without asking for an explanation. However, this "do now" is beneficial for students who are struggling to use and understand place value as they are adding and subtracting.
It shows students how each problem needs to be lined up in order to properly solve the problem at hand.
Another helpful resource for place value is this interactive place value chart. I see this being implemented in a classroom by the teacher saying a number and the class working together to put the correct number in the correct place value.
The Standards
CCSS.3.NBT:
Use place value understanding and properties of operations to perform multi-digit arithmetic.1
1. Use place value understanding to round whole numbers to the nearest 10 or 100.
2. Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of
operations, and/or the relationship between addition and subtraction.
3. Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 × 80, 5 × 60) using strategies
based on place value and properties of operations.
I truly love the way you thought about visual learners and your visuals are amazing. It very clear that this online resource can assist students with many clear explanations. You are going to be an awesome mathematician educator when you do teach and if you already do continue to rock like a math star!
ReplyDeleteHannah I love these sites for multiplication and place value, I can see using them in my class with my 3rd grade students. You are right it is a great way to differentiate and help our students who need that extra support. The sites look user friendly and straightforward too! Great finds!
