Math Interventions Understanding Foundational Skills for Number Sense- These are Prerequisites for student success in multi-digit computation. This comes before or simultaneously during instruction of computation. Mastered in Kindergarten- Number Concepts: What is it? 1. Identify the number instantly in standard form 2. Identify number in its variance 3. Can associate a “number” contextually 4. Recognize where it is in different ways ( 1, 61, 314) Q: How do you know a student has mastered Number Concepts? A: Number Concept Markers 1. Lexical entries for number (develop language for numbers) 1,2.3.4.5.. Counting starting at zero and non zero positions By end of K master counting by 1, 2, 10 from any number both forward and backward 2. one:one correspondence with sequencing, Conservation of Number: I count from any side it doesn’t matter it is still the same number (this is the beginning of number concept) 3. Visual clustering: Recognizing numbers up to 6 is called subitizing.. Having a visual image of numbers up to 10 in the minds eye. (NO Counting) 4. Decomposition/Recomposition: when you can see a 7 as 3+4, 5+2, 6+1.. this is mastered not by using blocks or other manipulatives but by making a mental picture of the number… (90% of K students have not mastered this by the end of their year) Instructional materials most effective are Number cards with different arrangements of these number combinations Kindergarten Sight Facts: 1+1, 2+1, 1+2, 1+3, 3+1, 2+2, 1+4, 4+1, 3+2, 2+3, 3+3, 1+5, 5+1, 2+4, 4+2, 4+3, 3+4, 5+2, 4+4, 6+2, 2+6, 1+7, 7+1, 5+3, 3+5, 5+4, 4+5, 3+7, 7+3,6+4 5. Form Numbers correctly 6. Concept of equality
