Unit 12 Math Test

This week in math, we will continue working on unit 12. This week we will focus on one-tenth more or less, one hundredth more or less, and adding and subtracting multi-digit numbers with decimals.

Please be aware that our standard for adding and subtracting decimals specifically states that students will perform this work with the use of manipulatives and models based on place value. Students will explore addition and subtraction of decimals to the hundredths using manipulatives, visual models, discussions, estimation and drawing.

This week in science we will begin learning about the classification of rocks. Rocks are classified into three groups; igneous rocks, sedimentary rocks. and metamorphic rocks. Rocks are classified based on how they are created.

Igneous Rocks-Rocks that are created when lava (above ground molten rock) and magma (below ground molten rock) cools to form rock. You can tell the difference between the types based on the size of the mineral crystals. Lava formed igneous rock have small to no crystals because they cool quickly. Magma formed rocks have very large crystals because they cool very slowly.

Sedimentary Rocks-Rocks that are created when the sediment of previously weathered rock is pressed together. Sedimentary rock can usually be identified by the different colored layers in the rock.

Metamorphic Rocks-Rocks that form when Earth's processes change the mineral grain of other rocks. Metamorphic rock can form as a result of high heat, high pressure, or a combination of both.
