Add by Counting On - Sums to 20
š§ Save your brainpower! You don't have to count both numbers from scratch. Start with the big number and just count on the small one.
Concept
Counting on is the fastest strategy for adding small numbers. Why start at 1 when you can start at the big number? šÆ **The "Grab and Count" Strategy:** **Example: 14 + 3 = ?** 1. **Grab the Big Number:** "Grab" the 14 and lock it in your brain. Say it out loud: "Fourteen!" 2. **Count On:** Hold up 3 fingers. Say the next numbers out loud as you tap your fingers: "Fifteen, Sixteen, Seventeen." 3. **The Last Number:** The last number you said is the answer! So, **14 + 3 = 17**. This trick works even if the small number comes first! (For 2 + 15, grab the 15 and count on 2!).
