**Description:**
Students will investigate what happens to the number of ants at a picinc when 100 more ants arrive at the picnic. They will explore this concept using a slide presentation followed by a partner game.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
**Standard(s): **

[MA2015] (2) 11: Add and subtract within 1000 using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds. [2-NBT7]

**Title:** Multiplication Facts, Facts, Facts and Some Reese's Pieces for Snack!!

**Description:**
This lesson teaches the basic math multiplication facts in a fun way so that students will want to remember them. Knowledge of all multiplication facts will help with learning subsequent skills in longer multiplication, division, fractions, etc.
**Standard(s): **

[MA2015] (3) 5: Apply properties of operations as strategies to multiply and divide. (Students need not use formal terms for these properties.) [3-OA5]

**Subject:**Mathematics (1 - 3), or Technology Education (3 - 5)

**Title:** Fun with Fractions

**Description:**
In this unit of five lessons from Illuminations, students explore relationships among fractions through work with the region model. This early work with fraction relationships helps students make sense of basic fraction concepts and facilitates work with comparing and ordering fractions and working with equivalency.
**Standard(s): **

[MA2015] (2) 3: Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends. [2-OA3]

**Title:** Food Pyramid Power:

**Description:**
In this six-lesson unit from Illuminations, students use algebraic thinking to explore properties of addition. The food pyramid is the starting point for these explorations. The learning experiences foster facility with the process standards of communication, connections, representation, and reasoning and proof.
