Building Equal Expressions with Snap Blocks™Play this 2nd grade math lesson
Snap Blocks lessons let students build and evaluate expressions with multiple addends (like 3+4+6 = 1+6+6), to build understanding of the equal sign. We increase the difficulty by increasing the number of addends on each side of the equation, using larger addends, and more. This series ends with quick true/false, equal/not equal, and less than/equal to/more than lessons, to build fluency and efficiency. You can also view the Snap Blocks™ tutorial.
Addition using Compensation Buckets™Play this 2nd grade math lesson
One of the most efficient mental math strategies is to turn hard problems into “friendlier” problems by making one of the addends a multiple of 10. For example, turn 23+38 into 21+40 by removing 2 from 23 and adding it to the 38. Kids start with smaller 2-digit addends, and when they’re ready they use 3-digit addends. Check out how we made this fun by using a bucket metaphor!
Adding and Subtracting using the Function Machine and T-chartsPlay this 2nd grade math lesson
Our mad-scientist function machine and t-chart create a fun setting for lessons that get progressively more challenging. Students complete either the machine’s output or the rule. Students work on +/- 10, +/- values of 1-9, and more. You can also view the function machine tutorial.
Addition Using the Open Number LinePlay this 2nd grade math lesson
The open number line is a powerful tool that helps students visualize making jumps forward and backward on a number line and use a variety of strategies for both addition and subtraction. These strategies include “Making Jumps of 10” (e.g. 79+33 = 79+10+10+10+3) and “Using Landmark Numbers” (e.g. 79+33 = 79+1+20+10+2). Students learn flexible thinking and efficient, accurate problem solving. You can also view the open number line tutorial.
