## Immediate need: students in level 4.2 math need a protractor

All students in on level math are working on geometry and will need a protractor to complete their classwork and homework. You can get a protractor pretty much anywhere that sells school supplies. The following link is for a protractor at Staples. (It is \$0.49)

## General Notes

• School starts every day at 7:40 a.m. Please make sure to have your students on time to begin their day.

## 4.2 Math

Last week students started the geometry unit. The main concepts that the students will need to know are: lines, points, rays, line segments, parallel/perpendicular/intersecting lines, types of angles (right, acute, obtuse), the classification of triangles (scalene, isoceles, equilateral vs right, acute, or obtuse), and the attributes of basic geometric shapes. Triangle classification, specifically, understanding how a triangle can have two names, tends to be tricky for the students. Quadrilaterals also tend to be a trickier concept- mainly because most students struggle to remember the attributes that differentiate a square from a rectangle. The biggest revelation is that a square is a type of rectangle but a rectangle is NOT a square! This comes from a rectangle having two sets of congruent sides, where a square has all four sides that are congruent.

## 5.1 Math

We are moving from a difficult unit (Order of Operations and multi-digit addition and subtraction) and into a unit about Decimal place value and addition and subtraction of decimals. In fourth grade math, students are only required to know and understand 2 decimal place values (tenths and hundredths- the two immediately following the decimal). In fifth grade math, students are required to know three place values after the decimal (tenths, hundredths, and thousandths). Additionally, students need to understand that place values to the right of given place value are 1/10 the size of the place value to it's right. This gets challenging when we introduce more place values. Lastly, students will need to know how to write decimals in standard, expanded, and word form. Expanded form tends to have two different notations that are shown- for instance, you could write 12.09 as 10 + 2 + .09 OR (1x10) + (2x1) + (9 x 1/100). The second notation tends to be the most commonly observed. This week, we are working on rounding decimals to the nearest hundredth using our knowledge of place value and comparing decimals.

## Science

Students are completing the light and sound unit this week. The unit test will be on Thursday, Feb. 16. Students received a completed study guide over a week ago and teachers have been encouraging students to study nightly.

## Social Studies

Next week we will jump back over to social studies and pick up where we left off after the American Revolution. The unit is titled "the New Nation". It will consist of how the colonies came together to from the United States and what the government system looked like. If your child was here last year for third grade, you probably remember them having a difficult time understanding the differences between the three branches and levels of government. This unit also reviews those same things and adds other things like the Bill of Rights. Students will need to know what the amendments are of the Bill of Rights and what right each amendment gifts them. It is a very interesting unit!

In reading students will continue to work on a plethora of reading topics throughout this nine weeks. Some of these include:

• Figurative Language (simile, metaphor, personification, idiom)

• Historical Fiction

• Personification

• Main idea and supporting details

• Domain-Specific Vocabulary

• Summarizing

• Theme

• Allusion

• Library lessons
• Text Structure

## Language Arts

Students will work on Lucy Calkins Literary Essays. They will also be working on a variety of grammar skills throughout their writings over the next 9 weeks. Some skills that students will be focused on include:

• Prepositions and Prepositional Phrases

• Abbreviations

• Transitions
